2.3.1 - QoL Changes and Crash Condition Fix

• Fixes the reoccurring crash that happens sometimes there are no more rows to iterate over. This happens sometimes when the program reaches the end of the image strip. (For ppl experiencing crashes please update to this version!)
• Changes the minimum allowed image height from 50% of the rough height to 40%, this is to give more lee way for those that upload to MangaDex, where small sizes are more welcomed than larger ones.
• Program now saves the latest input folder path/directory and can set it as the initial directory that the Browse Dialog opens at. Should be helpful to people that use the same input folder, no more renavigation to back to that folder.
• Now the progress bar will take into a count if you have a subprocess to run after stitch (it will reserve 20% of the process of each input to display it's status/completion). So now it should be a bit more representative of the entire process progress.

2.3.1 Fixes & Changes

• Fixed another crash condition related to resizing image files, a pretty rare case when you get a raw image with a single pixel height and it can't resize it down.
