Here we go, keep in mind I wasn't trying to do the best job, more a matter of show how things could be better implemented. One of my reasons for doing it was that I have a 1920x1200 screen on my laptop - which is barely enough for all the modules I need to have open just to get some of these basic functions.
Click on the pic for a full screen cap - it shows the modules I'm currently forced to use to get the basic playback features I want/need.
1. Extended Layer Controls (From left to right)
Display On/Off with Thumbnail (Like it does now - but with a thumbnail in there).
Lock Layer
Play/Pause Buttons - these need to be separate buttons (for midi).
And keep Opacity as it is now.
2. Fader Controls
This should be set to ON by default (not 10 layer mode like it is currently although I imagine others use the default so a setting in the preferences to open on either would be good.
Transform buttons ala V4:
Fade button & timer - again like the V4 to do smooth fades from one bus to the other.
Cut button - instantly switch to the opposite bus.
3. Hide button for master panel.
The ability to hide this will help those with smaller screens and I find myself rarely using these settings.
4. Random Frames Button
Press for random frames, based on the current speed. Possibly a drop down menu switch to be random based on audio.
5. Freeframe FX
A tabbed panel to switch between the current Animation FX and a Freeframe FX panel.
Then something similar to the current module but with at least a few default/standard dials and switches that can be assigned midi.
6. MIDI Control of preview selection (See linked pic)
So you can switch your panel via midi or keyboard shortcut. Possibly control for all those buttons but MAIN & PREVIEW and a switch between each one button (so if need be you can just use 1 key to switch between the 2).
7. Ability to right click on a button/dial/switch and set its current state to SET AS DEFAULT.
This is especially obvious when settings such as BLUR as it is set way too high by default or that the option normalize isn't ticked by default.
