D E S C R I P T I O N:
This is an open source Maya script written in Python (PyMEL).
It is a dynamic and flexible UserInterface (UI) to manage selections and poses,
which can be useful during animation.

F E A T U R E S:
- User can create and edit sets/selections/poses/members at any time
- All information is stored in the scene (works when referenced)
- Export/Import sets between shots/scenes
- There are a few pop-up menus (RMC=Right-mouse-click, MMC=Middle-mouse-click):
-- RMC on set-menu (top row): Create/Edit Sets and adjust UI (dockable, hide bar)
-- RMC on empty set-area: Create Selection/Pose
--- RMC on Selection/Pose: Create/Edit Selection/Pose/Members
---- MMC on Selection/Pose for extra commands (keyframe, reset, ..)

U S A G E:
Put the file prSelectionUi.py in your Maya scripts folder and execute:
- Python:
import prSelectionUi
reload(prSelectionUi)
prSelectionUi.UI()
- MEL (for marking menu, ...):
python("import prSelectionUi");
python("reload(prSelectionUi)");
python("prSelectionUi.UI()");

V E R S I O N S:
2012-12-25 / 0.9.8: Pose % items added to Pose middle mouse click menu // Autofocus on panel (tool shortcuts keep working)
2012-12-15 / 0.9.7: added option "UI: toggle tablayout" to switch display between tablayout and drop down menu
2012-12-12 / 0.9.6: bugfix (maya crashed for some users) // does not work with older sets
2012-12-11 / 0.9.5: loads faster, no crashes // changed mouse-click menus // new members UI // tabs are now called sets and in optionMenu
2012-04-20 / 0.9.3: pose support added // tweaks (button ordering,..) // can't read sets from old version
2012-04-15 / 0.9.2: tweaks (no popup when changing member status, show/hide shape visible in button,..)
2012-04-13 / 0.9.1: removed limitations // new features // can't read sets from old version
2012-03-01 / 0.9.0: first version

T O D O:
- member window close scriptJob for warning when there are unsaved changes
- search and replace for members (give user string output, input field, they can edit in editor of their choice)
- (maybe) popup when leftclicking empty set-optionMenu
- (maybe) shift/ctrl+mouse click on selection center button with maya viewport functionality
- (maybe) save set to shelf
- (fix?) when adding nucleus to selection: api error...
- (code) store pose nodes in dictionary with attr and values for faster 'pose selected nodes' cmd
