[FR] Add bulk actions for media items table

[Snake883]

Describe the solution you'd like

I would like to receive a list of downloadable content from a subscribed YouTube channel, and manually select what I want to download and place into a download queue. I also want to select which content I want to ignore/exclude/hide. I want to do this quickly, without sub-menus, without too many extra clicks or screens/windows, without extra confirmations.

Automatically downloading all channel content is not an efficient use of my resources.

I also want to delete content that I decide later that is not worth keeping.

My preference would be for a table of all channel content (sort of like the "pending" view), without a column of icons for [download, exclude, progress, status, etc]. And if I de-select "download", that also should presume I want the downloaded content removed and then excluded.
