1. Possibility to select different sizes for "circles" Eg if you are discribing a process where you have sycnhronous and asynchronous work, would be nice to be able to use different sizes in those cicles.
2. Filling the circles with differentc colous eg. brand colours like in thext editor.

1. Interesting idea. Would it make sense to support different shapes, like square or triangle also?

Yes, that would be a good idea too!
