Describe the improvement

Current behavior

Currently, when searching for a package (i.e. Syncthing), the search result UI will refresh every time a new result is found and shuffle the entries.

This can be very annoying when search discovers new entries for a long time, even though the package you were looking for has already been found. This can result in the wanted package jumping around the screen for some time.

Proposed behavior

Add an option "Sort by find/discovery time" that always appends new search results at the end of the list, so the result order and position is always the same.

Describe how this improvement could help users.

It's just a nice feature to have and makes search a bit more user friendly.

If this feature is wanted I'd be willing to write the implementation.

[marticliment]

It is in my plans to fix the refreshing issue, and to not refresh the entire list when adding packages.

However, I will see what I can do
