Do you know when improved gamepad support and custom keybinds will likely be available? Just as a ballpark?
It's tough to say, but it likely will be at some point after v0.7. The workload for these first 7 levels don't leave a ton of wiggle room. After Zol'gan is implemented, the next builds will be to revisit each planet and give each of them a new level. During these builds I am hoping there will be a bit more time to focus on stuff like this.
