Folder processing | Output parameter is not clean in understanding

[kezif]

Its not explicitly specified that program could work not only with one file but with entire folders.

Also its not hinted that output could be used not only to set output contact sheets name but specify folder in which file could be saved (with default file name i.e. 'original filename'.png)

To make is more clear I suggest to feature this use case on readme page and update output and filenames help section

For example vcsi . -w 850 -o screens to create screenlists for entire folder and output it to screens folder

Help section:

• for filenames: file path. Could pass multiple file names or folder path to process sequentially.
• for output: save to output file. Could pass path to folder to save contact sheets to this folder
