Hey, your mod is awesome and I'm loving it!
That said, I'd love to have a way to disable or toggle the special functions of backpacks. For example, the bat pack's night vision is useful in most cases, but sometimes I need to see true light levels or the night vision does't work well (ie. the Nether) and it's lots of extra clicks to take it off and put it back on etc. etc.

Thank you for your work and time!

Ditto. Thanks Mrab :)

If I have the time, I might look into doing that.
