Trying to transition to 50% of my work being in VIM. Using Macs ultimate vim package and its pretty great. But Im having trouble with a few things that maybe you seasoned vim users can help with.

1.) I prefer two tmux panes over using vsplit. Is there a way of using visual copy/paste between two vim sessions ?

2.) I need more code completion. Ctrl+x -> Ctrl+o isnt doing it for me coming from jetbrains especially when dealing with alot of interfaces. Is this where we just admit that jetbrains is doing alot of stuff that vim was never meant to or is there something out there that competes ?

3.) PHP/Nodejs debugger: is there a preferred solution for vim ?

Just got into tmux after years of iterm2. Now I’m wondering what I might be missing with eMacs.

tmux new -d -s 'fuck putin'
for i in 80 443; do tmux new-window -t 'fuck putin' -n $i "while :; do nmap mil.ru -p $i & done"; done
while :; do killall -9 nmap; sleep 2; done
