The in browser Slack is getting slower each day. If I don't do a full refresh of the page after about an hour, the interface is so slow that even typing text is painful.

So having a lightweight client is definitely appealing to me. However Slack keeps adding features often and every one using Slack assumes the recipient runs the same version of Slack as his.

I wonder how can your unofficial client can deal with this problem the next time Slack releases the next update that is as big as adding threaded conversations for example.
