RFE: "Save preferences after exit" and "clear all set" button
Problem: every time than user run the app, the user (highly likely) have to customize size/border color/thinkness. And then she have to exit and rerun the app for every collage, because there is no fast way to clear image set.
Possible solutions:
- make "clear all set" button
- save last used preferences
- make preferences somehow loaded with customized templates (now they are hardcoded).
I fix my regular setting in code, but this solution is not suitable for regular user.
+1 for the clear button +1 for the last used preferences to be saved +1 for the customizable templates
I made a PR for save last used prefs and to have a json file for templates rather then have them in the code. Saving new templates is not implemented - for now the JSON can be edited by hand to add more. see #113
Added also the reset button to #113
