Same here! I picked up htop ~2011 and learned about mouse support in ~2014. :D

Also- if you're on a Mac and you use tmux I just started trying out the tmux integration with iterm2. Pros and cons but it's interesting to see first class OS windows for tmux.

Edit: add missing iterm2 reference. https://gitlab.com/gnachman/iterm2/wikis/TmuxIntegration
