After mods to stop party members from leaving and remove some time constraints

Hi I'm looking for mods to remove my two biggest annoyances in BG2. One I want a mod to stop party members from leaving. I'm ok with them being unhappy with me but don't want them leaving my party.

Two I want a mode to remove time constraints, say on companion missions and so fort. When I am out adventuring I like to get to things in my own time not the games.

Do mods such as these exist?

Thanks.
