I wish there was a setting to make it impossible to use items with a click/without a hotkey. Reason is, I was trying to move my (10 sec) bkb to another slot so I don't accidentally use it, and ended up using it. Then I realised how stupid this is. How often do you actually click items to use them? Almost never? There are other games that have the option to disable left clicks completely during gameplay when a button can be used instead (osu!) and it works well, no reason it shouldn't be in dota.
