Say for instance, I highlight 3 image files, or I highlight 5 text files then if I right click to press 'open' or if I tap enter then only those selected files can launch in whatever program is associated with them and it would be at the user's own discretion.
I thought that I could select 3 image files and that they could open in the MP 'viewer' but I found that it sadly currently couldn't:

Currently it's only opening 1 image instead of what I've selected. The same is for other files types. I hope this can be fixed later.
