Tip: if you're doing a lot of cropping and slicing of videos and you thought the new quick tools in Finder / Quicktime Player are a great improvement, try setting up IINA with slicing.lua and some keybindings for navigating your video + setting the slicing positions.
Make sure your ffmpeg command (in slicing.lua) is set to copy the original codecs and that it's using your GPU.

Cons
Con Like Apple, it does not standardize file size. Mixes up KBs, MBs GBs in the same column which makes it very difficult to review file sizes
Con Like Apple, shows the date of Today's file as "Today" instead of the actual date
Con Does not sync the "selected" folders (i.e. highlighted ones), but the "current" folders (i.e. the top of the visible tree.)
Con Does not show the fixed tree section in the left pane of a dual horizontal panes
Con Unstable
May crash unexpectedly, while clicking on something in the subtitles section in the right-hand panel, for example.
