Keybindings on PC, ME2 and ME3

I know I can't be the only one, but please please give us a patch to unlink ALL actions from a single key press. I can't count the number of times I died because instead of sprinting away Shepard decided to hug a wall or instead of going into cover just dive roll in front of the enemy. 

Maybe I'm in a niche with this one, but on Me3, please also remove the restriction to bind TAB-key. It is an essential key (because of non-existent multiplayer) but I use it in all other games to reload my guns. 

I would also be satisftied for now, if there is a mod that does this for legendary Edition.

Thanks
