Sometimes, I have a large "Checking" queue, both for downloads (torrent re-starts) and uploads (torrent finished).

So when Vuze tries to start downloading a torrent that needs to be checked, it uses a download slot (tracker has 5 slots max allowed) for nothing. The Checking process could even last >10min sometimes.

It would be nice if Vuze could:
1. Not waste a download slot for a file that is being checked (pre-check files before starting downloads, if not ready then try to temporarily download the next file(s) in queue until "Checking" is over)
2. Pre-check the file automatically (before being put in download state)

Is it possible to allow Swarm Merging with incomplete and complete downloads? The Wiki says this is not allowed.

Sometimes after downloading a package, you may find a larger package (like more volumes/episodes of a series), this is common with ongoing series. Using the existing torrent to merge with the new larger torrent would save bandwidth and sometimes you can't just drag & drop files because the names are different.

Right now, I rename one file and force a recheck (with the networks disabled) to force a torrent back to the download list, but this is a pain for large torrents and even harder to do in cases where several torrents have different files that can be linked to another torrent (Example; Torrent 1,2,3 all have distinct files, but each have "some" files that can be found in torrent 4).
