Not sure if this forum is really for ideas for the app, but in ChatGPT, having to manually select each individual chat when moving over to a project (or cleaning/deleting) is tedious and would be made so much better with the addition of multiple selection.
Welcome to the community @ShawnH80 and great suggestion! I tagged it with feature-request and will flag it to the leaders. I don’t think there is any easier way - currently you can either just drag that chat into the project (the fastest) or click on the three dots and select “Add to project”.
