A lot of apps now have this gesture, if you double tap on an image but keep dragging after the second tap it should function as a pinch-zoom. Can we have this for opened media please?
See Google Maps for an example.

This already exists for images

The summit app for mobile (which is the community you are posting this request in) already has this excellent feature.

I thought there was a setting I missed but it just straight doesn't work on my end: https://youtube.com/shorts/wTYZ8ACkLiA
Is there any debug menus I should look into or any technical details I could give?

Hmm, I see what you're saying.

I could be wrong, but that doesn't look like the Summit app to me (at least not the way mine looks). Sorry if this is a redundant question, but are you actually using the Summit app?

Based on the video it looks like you are running into a bug where some animation is getting stuck. It's likely a bug caused by some combination of settings. Can you please provide the settings you are using? To share your settings, go to Settings > Import & Export settings > Copy settings for debugging and then paste the text here or you can DM me. Thank you!
