We are in the early alpha stages of a new messaging platform that bears a lot of similarity to Slack. We are currently evaluating our options for content editing (right now we’re just using very basic contenteditable) and wanted some feedback on using ProseMirror? We like the fact that it is flexible and supports markdown in the examples, but the biggest concern is performance. Because inline, on-the-fly editing of messages is common along with running on mobile devices, we want to make sure the editor we choose won’t cause any serious performance impact for our users. Any feedback is appreciated, and if you want to see what we’ve built thus far: https://app.courio.com
Thanks
