I haven't posted any suggestions here lately, as I know you have your hands full
If you ever feel like you have an abundance of time to add new stuff to this mod, just let me know. I have a page of minor mod ideas noted down
Two variants of the climbing mod I can think of:
v1: When weapon ready, climbing is turned off. When weapon sheathed, climbing is turned on (and might as well be more aggressive in activating.)
v2: While weapon ready, climbing skill is debuffed. (While we're at it, Jumping and Swimming as well?)
