(1) A common problem I face when debugging disassembly is tracing the movement of data across registers in reverse to figure out what was in a register and why. A second problem I commonly face is trying to figure out where a jump instruction is going.
It would be awesome if RemedyBG could figure out what "body" the cursor is hovered over (register, register+offset, asm instruction, instruction address, etc...) and automatically highlight all matches in view.
(2) Learning assembly requires a lot of looking up in manuals. It's a slow and painful process. Even if I memorized what a particular instruction does, it can be easy to forget the ordering of parameters, and important side-effects of the instruction.
It would be awesome to show a tooltip for a selected asm instruction and/or a quick link to more information.
Thanks for your willingness and tenacity to write a debugger! I hope it's fun and lucrative enough for you to continue!
