Feature: Add search to gui application to filter images

[mylinuxforwork]

Hi,

In the current version you’re showing all images as previews in alphabetical order. In case of a large collection it’s difficult to find the right image just by scrolling.

That’s why I request a search function implemented as a search field above the thumbnails to filter the images by filename. The list should get filtered everytime I type a character in.

Thank you for considering this feature.
