If a user creates a Maemo5 target for the first time, a bunch of files are generated in the debian/ directory. The user can then modify these files with a text editor. However, if the user with little experience from Debian packaging makes a mistake while editing the files, there is no clear way in GUI to get rid of these files. If the user removes a target and adds it back, the same files are still used, resulting in a state where the user cannot restore a clean slate (without manually deleting the debian/ directory).

When removing a target, the IDE could ask the user if they also want to remove the deployment-related files (and also remove them from the repository, with a checkbox for that).
Since we already have a dialog asking whether you really want to delete the target, the same dialog could be extended with a couple of checkboxes for this purpose.
