In the campaign sometimes you have to collect a command lying on the ground first to obtain it permanently for the level. Would be cool if that would be also possible for the leveleditor. In that fashion you can build Metroidvania-like stages or have even more possibilites for potential brainteasers. The only difference is that it shouldn't persist when you restart the level.

I agree, as long as every change like this can be turned on/off, because people will always have different approaches to things.
It's important for games to not be too complicated if they are not trying to be.
