Not easy to cleanup ppa for ubuntu-mobile; needs mass deletion or better filtering

Hi,

It's quite hardy to drop packages from ppas en masse. I needed to do this in the ubuntu-mobile ppa today:
- remove packages from gutsy (which we backuped ourselves beforehand)
- remove packages which were just "snapshots" of hardy packages (backports if you prefer) for hardy (this is for a use case a bit complex to describe)

What I did was ^F/^G gutsy in my browser, selecting the package for deletion and submit, but I could only do this for the first 50 packages, and we have more packages than that, so suddenly I was stuck.

For the other change, I was looking for ~804 in the version string and was also reading the .changes file to make sure that I wasn't dropping a backport with useful changes not merged in hardy.

It would be nice if I would be able to do so more easily, perhaps having a big list of packages instead of only 50.

Another option would be to see 50 packages per 50 packages and select them for deletion.

I'm not quite sure I could easily express in a filtering criterion that I want to delete backports from hardy since I need to check the changelog, but I could have filtered by version number; not sure that's very useful in the general case though.

Bye,
