I love that the new designer makes it easier to edit on small screens like my laptop. Now, I can focus on the stuff I currently work on and move everything else out of the way.
There are some things that I noticed, though:
I like to use the dark theme (reminds me of VS Code). However, I find some of the menu text really hard to read. It could use more contrast.
The list of timers is not that important that I need to see it constantly. The timers could appear in the component tree, instead. They take away valuable space on the screen.
Are you still wanting help about your 3rd issue? I’m not sure but I don’t think the request method is intended for reading a text file stored on your own website. There is probably a better way to do that.
