What you want IINA to do:

In the welcome window, enable the "Resume" action under "Playback" in the menu bar, and accordingly any cycle pause or other play-like key bindings, to open-and-resume the highlighted media item at the top of the recent-media list.

It may be sensible to enable similar actions like "Next Media"/"Previous Media", too.

What IINA does currently:

AFAICT, in the welcome window (Preferences > General > Behavior > At launch: "Show welcome window"), there is no menu-bar action or keyboard shortcut to play/resume the highlighted media item. Only cursor-clicking the item will resume it.

Note that the up and down keys will play next/previous media items from the welcome window. This seems like the equivalent of an open-and-next/previous-media action.

Why you think this should be added:

This would extend keyboard-driven operation to application startup and help enable automation via AppleScript, MacOS Shortcuts, BetterTouchTool, etc. (Personally, I'm trying to configure a remote-control button that launches IINA and resumes the last-watched video.)

Thanks!
