Hey!
Here are my 2 cents building on other’s work from this thread:
This one is with emboss (same color and style as the outer white edge).
And this is more like a glowing overlay, like some seen here before.
The idea with these (if not clear at first sight) is that S for Sublime, and angle brackets (inequality signs) are merged into one symbol.
Other idea I liked which either I will explore further, or others can take this direction further if they like:
Code in the background with a simplified interface (tabs, code, minimap, etc) exposed within the white borders.
Feel free to work towards this direction if you like it, I might do so too.
