Finally , a keyset search bar!
Found a few small bugs tho.

If you press Shift or Blue Shift the text in the search bar disappears.

This makes it hard to search for a mix of numbers and letters.

Also holding the key to get a number on the first digit doesn't work.

Open Pierogi, Select Keyset by Device, Hold 'e'.
The expected outcome is '3'

Finally is it supposed to be case sensitive?
It currently isn't but I was expecting it to be.

Cheers for the update.
