I've been absolutely loving treesitter. It's come a long way and it's been absolutely great for things like folds, motions, highlights of course. Now that I've finally gotten familiar with writing my own queries I can extend the existing plugins. As an example I've added folds to blocks of multiple consecutive comments in JS and Ruby.
well, i eschewed motion plugins for so long, but i recently installed easy motion, to quote "maybe use it minimally so i don't have to change my work flow too much". i pretty much gave up using w, e, b and f within a day of installing it, replacing each of them with a more efficient reach for the same number of key presses. similar situation with ultisnips, thinking it'd be overkill for my needs. in other words i was worried it would save me TOO MUCH time pffft. these both work really well with opening zsh commands in $editor too.
Someone else in the thread recommended pounce as well for that. I actually used to have hop installed, but I just never would use it. The default motions seem sufficient for me.
