List Sync: hide returning Entries from previous Runs

[rpgstuff-pingo]

Suggestion

List Sync is a great feature, i love it .

I mostly use MALSync with kitsu as master source so i have the most anime or anime-like videos on crunchyroll tracked.
Some Errors like "NotFoundError: Not found." are expectable and will shown on every list sync Run.

So my wish were that the returnning errors will not shown in every run so I think feature in one these implentations were nice:

1. individual click on on a media to ignore it it in further List Sync Runs
   or
   2.make a setting in MALSnc-Option to ignore showing know issues from previous runs

In both cases the entries should be added in a foldable category(number of items) "know issues" or "old issues(number of items)" with folded state so the items will not shown till the unfold it
