From time to time I try to switch to IDE or another editor, but I easily get lost. I work on a big screen so I want to split my window into 2/3/4 parts to see multiple files next to each other. Vim has built in shortcuts for that and in my vimrc I added 2 lines to make custom shortcuts that are even simpler. How do I do it in Intellij? The most common way is to use mouse, which I find annoying since with Vim I'm able to use keyboard 100% of the time. There's also a way to add shortcut for that, but it's buried deep into settings (Settings -> Keymap -> Main menu -> Winddow -> Editor Tabs -> Split vertically / Split horizontally).
I guess what I'm trying to say is that what you consider "poor version of (...) functionality that comes out of the box with the most basic of IDEs" is enouh for me, and I've been coding in multiple languages over the last few years. On the other hand in other editors I have to slow down my development due to lack of good editing shortcuts or I have to invest significant amount of time into making sure that I can recreate these or similar shortcuts.
