Too much RAM usage
GoodNotes takes several gigabytes (sometimes more than 10 gigs) of RAM on my computer for just 5 documents. These are not fancy documents, just one note with 17 pages, one grayscale textbook PDF around 400 pages, and 3 more notes with about 5 pages each. This definitely should be fixed. This happens when the GoodNotes is running for several days, and seems like GoodNotes will never release acquired RAM, which is something any programmer should have learned in his/her Introduction to Programing course. Chrome, which is famous for its RAM consumption, "only" (I used the word loosely, comparing to GoodNotes with 5 pages opened using 11 gigs) uses 12 gigs with about 45 opened tabs.
Please fix this, thanks!
