I have few questions for you:
1- Infuse is not processing files that contain a pipe (|) as a character. This character is not prohibited on Linux
What do you think about offering a feature for sanitizing/renaming those filenames? (eg. replace non ascii chars with their equivalent, replace the other chars with an _, and lowercase everything).
2- The movie 10x10 is available in themoviedb.com but it is not well recognized on my side (tried both 10x10_2018.mkv or 10x10 (2018).mkv).
3- Don’t you want to allow adding remote HTTP(s) URLs as a source to a web server + directory listing?
4- Does Infuse process the metadata while the use is on another app?
5- Regarding Family Sharing, it may be an interesting idea to consider allowing users upgrade the app without using a third party website like trakt.tv. This process should be handled entirely by finecore.
6- Cleaning up and simplifying the UI could also be great. For example, grouping somehow the 5 last menus (follow infuse, share with a friend, note infuse, config guides and sent us a mail) from the parameters to a single one.
