Would be lovely to be able to filter what kinds of events to learn when it comes to timecode learning - for example, last night I was simultaneously learning some SMPTE stamps while also making cue edits in real time, so the events list stored any macros that I hit while we were learning. Right now I just go back and delete those events from the Show Control List, but it'd be great to have options to say things like "learn all," "learn cues," "learn macros," etc.
Mike, while we ponder this extension, it is worth noting that you can exclude specific macros from being learned in SC events. There is a field in the macro editor to set that flag. It's not exactly what you are looking for, but should help.
