• Default: Like it is now
• Instant: One left-click will equip it (how Charset did it)
• Rightclick: Like Instant, but a right-click

This may be useful on servers with protection plugins / mods that disallow block breaking.

Additionally, changing the unequip behavior should be considered as well:

Just wish there was an option to remove the bag that wasn't bound to sneak. The amount of times I placed my bag without wanting to induced painful levels of facepalm.

So perhaps a second keybind (that defaults to Shift + B) or reusing the existing one (Sneak + ) to place the backpack instead of sneak + right click would be useful.
