Wow, wrong place to reply. *facepalm* I am so stupid.
Anyway, as it's the right mouse button you usually work on with assembling your parts (to hold them and stick them together) you're not really that much in danger of making a mistake of hitting your sword (with the left mouse button) and disassembling it mistakenly. So for me, I don't think it'd be that much of a nuisance to have the crafting table as the disassembling table.
