Humdinger added some code to improve the tracking of rows, and handle possible dynamic updates of rows.
Thank you Humdinger for your additions!

2nd attempt to make things work better with searches containing added date rows.
Counts are still off, but a bit closer than before.

Partial fix for torrent counts thrown off my "Torrents added" date rows.
Trim Top still needs a fix, but it may be a while before I track that one down...

Also remove "Previously Partially Downloaded by you" as who ever is seeding this is hardly online.

Found another case where the "Trim Top" button didn't load, and fixed it. Also discovered this breaks on searches that return extra rows that group torrents by the added dates. That is a current bug, and will require more code to fix. I may just remove all the rows with those dates to simplify things in a future release, but until then be aware this script won't work on such search r###lts.

Fixed an error with the new counters that prevented the "Trim Top" button from loading.

Trim Top was off by 1, now can remove just 1 torrent. Fixed case with no seeding or leeching torrents so both trim buttons still work.

Added a "Trim Top" button to trim the torrent list from the top. Click the Rows Removed button to see it.

Fixed some bugs with counting, and now hide the remove button when done with it.

Updated button labels to more accurately reflect the current state.

Trim to button now appears even if no seeding torrents are removed.
Leeching torrents are now removed as well as seeding.

A few style changes. Added a Trim button to select the number of torrents to zip after removing ones already seeding.

2nd attempt to correct the total count left.

The correct total number of torrents is now displayed after using the remove button. (Bug Fix!)

Minor style changes. Added total of torrents removed, and total remaining torrents.

Added update and support links.
