This is an attempt to improve usability a bit. Currently the visual location of the selection pointer is offset from where the actual pick location is (which seems to be the upper left of the graphic). This moves the visual of the blue pointer point closer to that location. Or maybe there's a better way to do this?

Grid support with shape selection tools

Is there support for matrixs?

A blue-sky feature would be the ability to have multiple LED strips, so that I could create a scrolling vertical pattern, or scrolling text.

When toggling back and forth through frames it would be nice if the keyboard arrow left/right keys could be used for back and forward.

I made a project, saved it, and made it public. But if I go to Projects and View it, it seems to be showing old data from when I initially was working on it, not the currently saved version.

Create a tool that copys the code to the clipboard.

A mouse button action would be more intuitive and easier to use. Perhaps click to toggle the selected LED between the selected colour and off.

As an extra enhancement, how about having 2 currently selected colours, one linked to the left mouse button and one to the right mouse button, each with "click to toggle" the colour as above ?

Notes

Look at the illustrator UI as an example of what might be possible.

When using the Forward button, if on the last frame and clicked again could it loop back to the start?

Used for people sewing leds with unique patterns.

Look into text base library for fast led

What about having the "Create Pattern" button automatically jump back to the start when clicked? (ie. Remove the need to manually move the slider back to the start before being able to click the button.)

When I first went to the Me page, the name field and Save button didn't even register to me since it was almost the full page width. I think I thought the Save button was a page section divider of some sort. Here's a UI change suggestion.

I was wondering if the Select and Unselect buttons could be combined? Then when clicking it would select, or unselect, based on if the pixel was already selected or not.

Purpose

We should look at the last led that is not black and make the necessary subtraction of frames.

Original Post

I tried 8 LEDs, 16 frames, Bounce right

When the lit LED gets back to LED 0 after the first bounce the next LED to light is number 7 so something is not correct

	//Frame 16
	leds[0].setRGB(0, 0, 0);
	leds[7].setRGB(170, 0, 0);
	FastLED.show();
	delay(500);

This seems to be the problem

Great a way to create an adjustable grid view

very very cool. could the code it outputs be a little more streamlined? ill admit I didn't play around with it too much, so forgive me if this is a feature. could the code output be at least optionally in the form of a for loop for example? and as a function?... after messing around a little more I see you can paint individual LEDs!!!! very cool feature and I see why a for loop wouldn't work. but when you use the odd, even, and forth could those be Output as For loop functions?

Would love to be able to adjust the size of the LEDs so that instead of curving like a snake I can view it in one row.
