[Feature Request] Bulk Analyze Selected Files and Analyze from the Media Management Screen

[Sulinde]

Is your feature request related to a problem? Please describe.

When Komga encounters errors in a file, the files are marked and the information is accessible in Media Management. Sometimes these errors require file-specific attention, but other times these are errors that can be quickly fixed in batches. For example, I have Komga set up as its own user so if I forget to fix the ownership and permissions on imported files, they will be inaccessible to Komga and an error is thrown on analysis.

The problem is that after fixing file permissions, re-uploading repaired files or otherwise resolving the source of Komga's error for many files at once, my options seem to be either re-running Analyze on my entire library which can be very slow or selecting each file one-by-one which is still slow and quite tedious.

Describe the solution you'd like

I would like "Analyze" added to the multi-select menu when selecting multiple comics in Komga and/or a button to re-analyze all (or selected) files shown in Media Management under the Media Analysis tab with error statuses.

Describe alternatives you've considered or other apps that can do what you want

I'm not familiar with alternatives to Komga, however Comicrack has a right-click menu for each library item that's similar to Komga's "..." menu and the multi-select toolbar, however it retains the "Update Book Files", "Refresh" and other meta-file actions whereas Komga drops its meta-file "Analyze" option from multi-select while keeping the collection/list management and delete options.

Another option would be to have a "lite" version of analysis, similar to how there is a Scan and a Deep Scan, that only analyzes files that failed analysis or have otherwise not yet been analyzed. This would not have to be part of the multi-select toolbar for comics or the Media Management screen, but could instead be part of the "..." menu on a Library next to Analyze or part of the Server Settings menu, under the Server tab next to the library scanning options.
