Interface lag when selecting zip files

[justalike]

Hey! I've noticed that when pointer is at archives (zip files in my case) it freezes the spf while calculating archived metadata.
If you have a large archive with lots and lots of small files there it will freeze the app for quite a long time.

In my case 450 mb archive with about 1mil files would take around 9-12 seconds to process.
Archives with many files but about 10-15mb take 1-2 seconds.

moreover, inputs are not blocked but queued when you try to move pointer up/down while it calculates.

I can confirm this
This need to be fix!

I guess the fix could be non-blocking input, and / or trigger extracting metadata with delay (while pointer stays on the file for longer than 100-250 ms)
just thoughts.

Yes, I will put the part of getting Metadata into the thread, and after getting the data, Send it back to the main program.

The performance can be improved by immediately finding only those metadata that are shown immediately. Then the rest can be lazy loaded if user goes to the metadata panel. If not, they won't be loaded.
My thoughts only, idk how to implement but lazy loading is pretty popular these days and effective too.
