Thanks everyone for testing! 
I’ve merged this: FEATURE: Add configurable mobile modal dismiss gestures - Pull Request #7 - VaperinaDEV/discourse-topic-preview-modal - GitHub
Configurable mobile dismiss gestures
This update adds configurable dismiss options to the Topic Preview Modal:
- None: no additional dismiss gesture
- Grip: shows a visual grip in the modal footer
- Gesture: allows the modal to be dismissed with gestures:
- swipe up when at the bottom
- native mobile Back gesture/button
Swipe-down dismissal is available in all modes.
The native Back behavior is especially useful on mobile: instead of navigating away from the underlying topic list, the Back action closes the modal and keeps the user’s position in the list.
The desktop modal is not affected by these options.
If you find this useful, consider supporting its continued development.
