Removing skins -> option to remove image set for that skin

[Gavrisimo]

On my demo board i have a lot of skins and im adding new ones and removing some that are finnished on a regular basics.

Dont know if im blind or what, but most of the time i forget, that after i remove a skin, the image set for that skin is still on ftp and the only way i see to remove that folder with images - is via ftp.

Wouldnt it be nice that after i remove skin an automatic check is preformed to see if some other skin is using same image set as the skin im removing and when it checks all skins i have installed it should do this:

• there are other skins(one or more) that are using same image set as the skin im removing - in this case do not prompt anything, just remove the skin
• there arent any skins that are using same image set as the skin im removing - in this case prompt me an option with "Yes" and "No" with question "Do you also want to remove image set the skin you are removing is using?"
  

Toughts?
