It would be nice to have double page support, be able to change whether to show first page alone first (and be able to set it in toolbar and keyboard shortcut).

I have not yet used the Manga Reader yet, I just downloaded it with flatpack.

I was trying to get a directory to my local partition with stored manga, but I saw the message from Manjaro, something along the lines of "This program runs in the background". Then it asked "quitting this program may result in a loss of data" or something like that, then there were 2 buttons, typical "agree" or "close", again, I dont remember. I just hit the cross button to get rid of the message. Last thing I saw immediately after that is title cover for Attack on Titan, then Manga Reader closed.

Every time I try to open it will stay for 7 seconds then close again. Functionally it allows me to click buttons and interact with it, it works, but closes itself after a short time.

Steps to reproduce:

1. Have "Page spacing" set to 0
2. Open 403: Bonus: The Prettiest Platypus 3rd anniversary Character Q&A!.cbz.gz (created from The Prettiest Platypus episode #403)

Expected behavior: No gaps

Actual behavior: Lots of gaps

Gap between page 1 and 2:

Big gap between page 3 and 4:

Giant gap between page 5 and 6:

When changing the panel layout of the manga folders and bookmarks, then closing the app, the app seems to forget its previous layout and reset to the default one, which is inconvenient for smaller displays, as shown in the video below.

It literally solved all my issues. I was trying to use Okular as it works with CBZ files. But since I used a touch screen, I could not get out of full screen. But this app does the trick and is much like Okular for the reading aspect of things.

I have a question, is there a way to make a bookmark of the page you were on? Also, is there a way to make it default to full screen (not a huge deal given the dilemma I was having when tying to use default viewer of Calibre where it was slow working with CBZ files and then dealing with Okular having no option to exit full screen via touch).

Anyway, thanks for making such a nifty app. ;)

PS: I would have sent this in an email, but I got error saying that your email can't be found.

This is more convenient to read Japanese comic

Would it be feasible to add smooth scrolling? I took a peek at the dependencies and code and it looks like this program uses a QT scroll widget (at least that's what I'm assuming what it is because a lot of the names are things like Qscroll or QGraphicsView, etc.) which should have smooth scrolling built in from what I can tell online, but in mangareader it's still lock-stepped.

I haven't programmed with Qt before, but I glanced at some of your code for parts that seemed relevant and glanced at some documentation and I think it should be easy to add but I might be missing something. (again, zero experience with writing in Qt)

I looked at https://doc.qt.io/qt-5.15/qt.html#ApplicationAttribute-enum for all mentions of scrolling and found https://doc.qt.io/qt-5.15/qt.html#ScrollPhase-enum which, while I can't find any explanations for scrollphase online, looks like it might be for smooth scrolling.

Steps to reproduce:

1. Open Manga Reader
2. Focus the bookmarks pane with the keyboard (by default it's B)
3. Press Enter

Expected behavior: Nothing

Actual behavior: Manga Reader crashes

Screen recording:

Steps to reproduce:

1. Have "Fit width" enabled and "Fit height" disabled
2. Have "Upscale images" enabled and "Maximum page width" to 2400
3. Open 454: Ask you.cbz.gz (created from The Prettiest Platypus episode #454, the contents of this episode does not contain anything triggering, but future ones do)

Expected behavior: The images to have identical widths

Actual behavior: The images have differing widths (despite all the images being 800px long)

Screenshots:

Steps to reproduce:

1. Open Manga Reader
2. Open a manga
3. Enter the last page number into the go to page spinbox

Expected behavior: The last page to be shown

Actual behavior: The last page is not shown

KDE changed the names of some of their packages which break dependencies very recently.
Ran in to this issue with the arch distro package, tried building from source and resulted in the same.

kconfig5 (5.111.0-1) breaks dependency 'kconfig' required by mangareader
kcoreaddons5 (5.111.0-1) breaks dependency 'kcoreaddons' required by mangareader
ki18n5 (5.111.0-1) breaks dependency 'ki18n' required by mangareader
kxmlgui5 (5.111.0-1) breaks dependency 'kxmlgui' required by mangareader
kio5 (5.111.0-1) breaks dependency 'kio' required by mangareader
kconfigwidgets5 (5.111.0-1) breaks dependency 'kconfigwidgets' required by mangareader

Not a programmer so I would make a pull request and fix these but I don't know where to start.

More specifically, this would be the previous/next archive in the directory of the currently opened archive

Why did you remove my request at implementing smooth scrolling? Because I find it buggy when I have to wait for the odd image to load when scrolling on a touchscreen.

When reading a manga, you can use Page Up and Page Down to go up and down a screen. It would be nice if I could press Shift+Space and Space to do the same thing. I bind Scroll Up to Shift+Space and Scroll Down to Space, but it's not quite the same

Steps to reproduce:

1. Open Manga Reader
2. Open a manga
3. Scroll down a number of pages
4. Open another manga (via the pane or Open Manga Folder/Archive menu options, but not through bookmarks)

Expected behavior: The current page number to be set to 1

Actual behavior: The current page number inherits the page number from the previously opened manga, though it is updated when scrolled
