Creative tips?

[Edit] Not related to creative mode – sorry, bad title, wasn't thinking.

Every once in a while, I come up with a 'better' way of doing something and then wonder why I didn't think of it sooner, like using Main Stage Quinn in my farming build because the melee attack speed from Rockin' Riff also affects harvesting tool speed. Or re-speccing the weapon I use in my critsplosion build after figuring out that the actual weapon damage is just about the least useful stat – crit chance and swing speed being the most important for that loadout.

What's got me coming here is mimics – my current method of dealing with them is to drop a couple of proximity mines before triggering them and then use smoke bomb & melee to finish them off, but I found myself wondering if other people have even better solutions that I just haven't thought of yet.

And beyond that … what else do y'all do that you think is a pretty neat thing that maybe not everybody knows about?
