Hello!!
I installed this applet on my laptop, running Debian 12 Stable, running MATE 1.26.0, and, although it works really well, the default button theme is completely different from what I like, and I couldn't find any options in the applet settings to change the theme.
I found the issue #1 and #15, are these instructions correct?
Thanks for developing this applet for the MATE desktop!!

These plugins have been merged with gnome-applets https://gitlab.gnome.org/GNOME/gnome-applets.
And they are in C now not Vala 👍

I was unable to get a lot of data as my priority was to stop the process. The following is the output on my 4GB RAM laptop with the window-title applet using 84% of memory.

Hi ! , Thanks for the awesome App
I'm getting some random crashes on 18.04 Beta 2 while changing Layouts , and /or customizing the taskbar ( like moving/removing from taskbar)
Thanks

Here are the window buttons in a usual window decoration:

Here are the buttons in the window applet:

As you can see, the latter are a bit blurry. I am using the arc-dark theme. Is there any remedy to this?

So far, Arc, Numix, and one other that I forgot but will find when I retest haven't worked. I'll poke around and see if I can figure out what causes it, but be advised that I have no clue what I'm doing.

window-title-applet should behave as similar as possible to the regular window titles. So, double clicking on the applet should unmaximized the current window, just like double clicking on a window title.

Add a third option to "Control only maximized windows" so that when the current window is not maximized, the window-buttons-applet controls the maximized window which is behind the current one (i.e. the last maximized window), instead of hiding the buttons. Also, the buttons should look "unfocused".
This is similar to how regular windows work. And also how Gnome's window-buttons applet works.

Also (perhaps this should be a separate issue), "Control only maximized windows" should be implemented in window-menu-applet and window-title-applet as well.

If I have configured mate-window-applets to follow current maximized window, and I move to another workspace, the buttons are still the ones from the maximized window in the previous workspace. They should be the buttons of the windows in the current workspace only, if not then you could be closing an app from another workspace, that's annoying.

This error shows up constantly on all three applets:

(window-buttons-applet:19310): Wnck-CRITICAL **: 17:17:54.909: update_client_list: assertion 'reentrancy_guard == 0' failed

It appears to come from these lines:
https://github.com/ubuntu-mate/mate-window-applets/blob/master/window-buttons-applet/window-buttons-applet.vala#L223
https://github.com/ubuntu-mate/mate-window-applets/blob/master/window-title-applet/window-title-applet.vala#L64
https://github.com/ubuntu-mate/mate-window-applets/blob/master/window-menu-applet/window-menu-applet.vala#L81

Apparently it's because that function is being called too often.

I've commented those lines and have been using the applets for a couple of weeks and have found no issues. Is calling that function really needed?
