I think using "move bean" action would become a bit more user-friendly with some small improvements. Feel free to disagree, and discuss!
It's nice that I can pick an arbitrary file using the file chooser button. However, in most situations one will be moving beans between config files that are already part of the same fileset.
I think it would be good to streamline the interaction for this specific usage.
1) The filenames presented in the combo box use full filesystem paths. Perhaps project-relative paths would be better?
2) Could the combo box be pre-populated with all the files that are part of the fileset(s) that the current file belongs to?
3) Does it make sense to suggest the current file?
4) Some form of SpeedSearch using only the filename (not the full path) would be welcome. Not sure what kind of UI control would be good for this.
5) Perhaps it's a good idea to preselect the last (target) file used, if it does not conflict with (2) and (3). That would help with the typical operation of moving various beans together into a separated config file.
