We have a brand new feature in EDProfiler: A built in GUI Colour editor! Plenty of features, I will let you have a fiddle (been working on it all day).
If you like it, feel free to donate, as there is more work to do on it (like adding avatars when I can figure out what the matrix does to them, and maybe a more stream-lined colour picker).
It lets you see what your chosen GUI values look like for almost every layout in the game. It lets you change them on the fly, it lets you click on a colour to blend that colour in to what you've selected, it lets you scroll through your profiles. It is very very cool.
Has the ability to switch to larger values and negative values.
It may have bugs, and right now EDProfiler's file size has bloated due to the colour picker. That is something I will address very soon, and bring it back down to a few megabytes. But for now, I've had enough coding for one day
Of course, if you haven't noticed in previous updates, it also has the new settings for 2.3, as well as quite a few bug fixes and improvements.
Enjoy!
