Leader key behavior

Hello, i was trying some things with the leader key, and i have some questions
Is it possible to change the time that nvim is waiting for the command, lets say now waits 1sec can it be 0.5?
Is it possible to change the behavior so i can do various commands without releasing the leader key?

You can change it to wait 200msec by setting the following.
:set timeoutlen=200
