Feature add a way to exclude directory

[german-rios-gonzalez]

Hi, first of all, I really love this app! thank you very much!

Straight to the point: Might you consider the inclusion of a mechanism to exclude a directory? In my case I was forced to rearrange my photo gallery directory structure to left out the screenshot directory, and other directories in my Pictures folder like my wallpapers.

The content of the above directories doesn't fit well with my photo gallery, that is the reason I use this app in the first place, I know is easy to rearrange the directories and just change the «Picture Directory» but I think there is a good value to add a way to exclude a directory from the app

Thanks for your feature request. Excluding a directory is something that could be considered for the future.
