Given Minecraft and specifically modded Minecraft's propensity to lag, mode switching on the Jetpack and Mining Laser can be a massive pain. I'm constantly finding myself pressing the key and switching to a mode other than I want, either because the key registers twice (thus keeping on the same jetpack mode or skipping two ahead in a Mining Laser), doesn't register until much later after I've already pressed the key again in frustration, etc etc.
Could we have an optional "Hover Mode" button for the Jetpack, i.e. a non-toggling button?
And for the Mining Laser, a "Previous Mode" button added to the current "Next Mode" button would be superb. A configurable "default mode" key would be even better, like configurable as a "Low-Focus Mode" or "Explosive Mode" key.
It'd also be nice if the Mining Laser had a non-block-destroying mode intended for fighting mobs without destroying the environment; you could use Low Focus. After all, low focus means wider beam, which would be more effective than a tighter focus against flesh; it's not a disintegrator, after all, and like the difference between a full metal jacketed bullet and a hollowpoint the narrower beams would do LESS damage against flesh.
