Yeah but that means you're stranded deep in the area without a part of your mobility (may be a major one if it's in the lava flats).
True. In that scenario I would probably take off my heat suit and rely on triple jumping and storm dashing to get me to the exit. You'll almost certainly take less damage from the ambient heat than you would trying to dodge raptors and lava pits with only one jump.
On the original point, I agree it might be nice to have a way to temporarily disable effects that activate themselves from your inventory. Maybe a toggle somewhere. And then maybe mini could be toggled back on as a double tap down. I still miss that every time I come across a little gap.
