collapsing - for feature conforms, is SOP. But wouldn't it be nice if you could get away from that onerous task for onlining in FCP? Not all projects need to be fed to Scratch or FTHD or somesuch.
Item 3, the Long Shot Problem - YES I entirely agree, and my suggestion to the Red team has been to allow you to identify/mark/pre-cook subclips from source clips WITHIN REDCINE before kicking out the offline version if they can't cook subsections with handles.
It is a bit of a punt solution, but if you're stuck cooking the whole clip, at least go through and subclip it in Redcine BEFORE you kick out your offline versions.
And do it by order or operations, not where it falls in timeline - so first defined shot is shot_001 even if at end of the shot. Second shot defined is shot_002, etc. This avoids complications if you go back in and cut willy nilly, esp. if you do overlapping cuts. Naming conventions using timecode get cumbersome and problematic as well - what if I want two treatments of same footage, or overlapping subclips? Etc.
