@skrommel  NICE! a spartan way to setting up, but it works.
improvements:
-small gui with Transparency Slider/Icon Size Slider,
-right-click-menu for icon to change the icon and del/add Folders and maybe recently used Folders, Window Level setting, Lock/UNlock position
-alpha blending for png files
-Ctrl+Shift+Drop a Folder to add Folder to the List
- a way to chose a Folder Path and name the menu item diffrently. exmpl. C:\privat\blah\temp, Menu Namen= Temp Folder
- save last position/change position for start

@VideoInPicture
Very good implementation of the Idea, but with .Net Framework 2.0 anyway, great work.
Looks more userfriendly to me.

Edit: worked first time, now crashing while right-click on trayicon and sometime at the start.
Edit2: How to close Configuration Window without closing the program? O_o
Edit3: Crash appears after starting the program but in a diffrent location.
)Edit4: Possible png alpha-transperancy with gdi+ [http://www.autohotkey.net/~tic/Gdip.Tutorial.3-Create.Gui.From.Image.ahk])

LClock relocates the Start Button to hide it and everytime I start PS Tray Factory, the whole tray gets covered by the start butto.
