I have two modes of operation that I switch back and forth between::
My bad. When I said Play / Pause I meant Record / Pause
To answer your points:
re. 'limit by time' option: toggling on the fly is unlikely to be possible, but we'll see if we can give you some warning that the feature is turned on before recording starts.
re. enabling / disabling logging on the fly. This won't be possible. But it should always be turned on and only disabled in a situation where we believe the logging is causing some problem itself.
re. keyboard shortcuts. We try not to use 3-key combinations, though we do use shift-ctrl-S for "Save As" because its a standard. The shortcut for play/pause is already a simple one - the space bar. Sounds like you want to be able to assign custom shortcut keys for some functions, but we wouldn't be able to add this as a priority.
The reason why I dislike the keyboard shortcuts is that I have slightly impaired mobility in my hands and three key combinations are particularly difficult to use. Most two key combinations are already taken, leaving only obscure ones. It would be a bonus if multimedia keyboard buttons for play / pause could be utilised as hotkeys.
I would like to add:
The in flight options should include an option to enable / disable system logging because sometimes I am working an a PC based app that needs it and sometimes on a web app where the PC system logs are irrelevant. (Although if you could capture the browser's event logs instead that would be fantastic)
