ConvertAll Portable: Custom Colors

I think we need common code for all QT-apps. Without that, registry keys becomes messy.
Say we have 2 or more QT-apps (like FreeMat and ConvertAll):

1. Start App A:
   • customColors key is created
2. Start App B:
   • customColors key is renamed to customColors-BackupbyB
   • new customColors key is created
3. If you change custom colors in A or B, the customColors key will be changed
4. • Case X:
     1. Close App B:
        • customColors key is removed
        • customColors-BackupbyB key is renamed to customColors
        • customColors changes are lost for A
     2. Close App A:
        • customColors key is removed
     3. nothing is left behind
   • Case Y:
     1. Close App A:
        • customColors key is removed
        • customColors changes are lost for B
     2. Use App B:
        • customColors key is recreated
     3. Close App B:
        • customColors key is removed
        • customColors-BackupbyB key is renamed to customColors
     4. customColors key is left behind

Suggestion: Instead of using -BackupbyAPortable and -BackupbyBPortable we should introduce something like -BackupbyPortableApps.com.
Each PortableApp uses the same key and the last closed set the original key back.

Ahh, too much html, but I hope you understand my thoughts

maybe something like this do the trick. Comments are welcome!
