I tried it. The first week I shared your opinion. But then something flipped. I configured and learned hotkeys to hide the file/services/... pane and ended up with something I can only describe as 'calm'. Only 1 or 2 panes of code visible, and all functions hidden but available.

The main detractor is indeed the hamburger menu. Vscode had ctrl-p, emacs has alt-x, and both provide a way to search for some function to execude. I hope Jetbrains is hiding something similar in its innnards, but haven't found it yet. Ctrl ctrl isn't it, at least for me.

I went all-in on Jetbrains Ultimate last year without regrets. The thing is great and powerfull, but it is hard to find what you need in there, and hard to find out what is the purpose of some functionality. I've actually lost usefull functionality: Something usefull but I don't remember the name and can't find it in the menus. I should spend some time spellunking in there. Even so, I hope they find something better than the hamburger or the zillion hotkeys.
