Idea: add a short GIF to the README.md that shows the actual client

Hi! Nice to see that the project is still being developed! :) I drop by every once in a while.

I had this thought that you could use a screenshot - or better, a short gif - that demonstrates roughly what the client currently looks like. The benefit here is that this could help attract more attention because the bar to first contact with the client wouldn't require installing a release or building from scratch, but one could just look at the video. The GIF could be as short as a few seconds with low resolution to save bandwidth and link to a YouTube video.

What do you think? I just thought I'd add my 5¢.
