Since a couple of days I have been trying out PHPStorm. So far I really like it, but I notice that for quick changes I tend to refer back to Visual Studio Code.
A light theme, you say?
Yes, I am one of those people who likes to program in a light theme. Apparently, that is considered odd by some:
If ( not exists ) create yourself();
I did find a theme called Github Remixed that came somewhat close to what I was looking for. I used it as a starting point and modified some of the colors and font (Operator Mono).
If you like this theme too, you can find the version I use on Github. There is probably room for improvement. Please feel free to contribute!
