This is a small/“simple” Quality of Life request: Add keybindings for the elevation up/down arrows in the Terrain Slice Vision.
In general, not having to move focus from whatever you’re doing to alter the view is handy - much like the benefit of keybinding the slice, xray, and building vision toggles themselves. In particular, working with dug-out chambers on multiple levels, it would make it easier to maintain position between the two (say for lining up a mining hole or have an intersection in the right place) by being able to keep the cursor somewhere relevant. Even if the “multiple levels” are right above/below each other, it can be a surprising hassle to keep having to go over there an click the arrows to change views if you work with it long enough.
I realize there might be useability downsides from this - changing the slice elevation always seems to lead to a brief hitch, and with a keybinding that’d be more noticeable (from the delayed cursor response) and easier to chain into one big hitch. And you might have some reason to want the cursor to be occupied when doing that transition (how you handle the cursor interacting with whatever it might newly be over, or elevation changes while in mid-placement, etc). Just because it /sounds/ simple doesn’t mean it /is/ simple Plus, “more keybinds” is often seen as undesirable (more daunting to new users, less console-portable, etc).
I know I’m more keyboard-biased than most in terms of preferences, so I have no idea how broadly appealing this would be. But it’s something I’ve repeatedly wished were present in my time with the game so far, so it seemed worth mentioning at least
