- The date and time picker is a bit small to use on mobile, especially the sliders. Also it would be nice to have the end date/time follow the start date/time + a given average duration (1 or 2 hours), saves a bit of tapping around.
- When posting an event URL on Slack, it only shows the description of gath.io, and not a summary of the event, which would be a nice UX touch.
Do you have plans to make it open source ?
Good job !
