There are so many things to like about PD (compared to Sony Studio / Adobe Premier), but there are many mostly simple things that could improve it further..
Here are my suggestions (that may be repeats of the comments above):
Ability to have multiple projects open at the same time (multiple instances of PD)!
Control/Keypress Options:
> more control over the forward backward movement, some user options between the frame / 1 second / 1 minute /clip jump points please.
> the space does start/pause - but like Sony Studio, i want another option to pause but return to point where i started the play.
> Keypress preferences - you can save them to a named set. But you cant 'select' a set to overwrite/delete etc. Would be handy to have predefined sets that are similar to other edit products.
> To un-split a video (with warning if that would change duration)! And re-link video with its sound.
> Keypresses to change the In/Out clip points (duration) frame by frame on the timeline.
> Keypress consistency - all modules (PIP/Trim/Audio Director/Wave edit/ etc.) to use the same keypresses for start/pause/zoom/etc as set for the main edit / timeline view.
Auto-Ripple/Auto-Crossfade modes
> when changing clip duration or anything that changes its duration (like speeding up) then i need the system to auto 'ripple' the following clips. In many cases it truncates the following clip without warning.
> ability to 'reposition/slip' a clip from its underlying source in the timeline (ctrl+drag)
> view the offest time and ability to re-set the sound back to match the video - when you extend the sound so it is longer that the video, it is quite easy to offset it from the video.
> Audio: Fade shape - when fading music it can be useful to set the prefered curve for that fade (again - see Sony Studio).
Transition 'extention' Mode when using Overlap?
> When changing a transition from A-then-B to Overlap, the clips move - causing a gap in the timeline. (see auto-ripple).
.. so could we have a way to EXTEND the two clips with ether a static frame or set of frames (like slow-mo) over the transition, so the overall duration does not change!
..though if the clips are in the middle of a longer 'source' then the overlap could simply move the in/out points of the clip instead.
Playback
> Do not return to the start when playing finishes at the end - a real pain when you are focussed on making small refinements to the end of a video.
> Playback speed - to be able to playback at a faster/slower speed for quick review (with sound up to 2x speed).
Flatten the Action Menu!
> There may be many things you can do to a clip but i find it tedious that some things are under sub-menus (magic things / tools). Would prefer all clip options to be in one single list, if screen space allows, and only sub-menu if screen is small.
Gain / Opacity control or 'mode'
> The system has nice capability to alter the gain (audio track) or opacity (video, if fade in/out has been chosen).
> But it would be really nice to be able to set 'guide points' so you can set these only at set gains/opacity levels. It is very easy to make a mess of these tiny control points!
> And/Or to auto enlarge the track when in Gain/Opacity edit 'mode' to make the settings more accurate.
Effects
> Ability to apply effects 'slowly' - like fade-in and fade-out - but for the effect.
Modify Clip
> It needs to many 'clicks' to set Fade-In/Out (one for the fades option, then which you want - in or out). Why not just tick in/out?
In/Out points on the Time-Line edit..
> these are hardly used - and always seem to 'snap' back together. But they should be useful for:
> setting a playback 'loop' (rather than just clip or movie)
> setting a section to copy / render / produce / trim
> setting a section to 'zoom' into
