What transition effects

I have a couple of newbie questions. First, what type of transition effects does Shotcut have? In particular I am looking for blurred dissolve, which swips and blurs one scene into the next. Also blur zoom.
Secondly, does Shotcut support plugins, which would allow third parties to develop their own transition effects?

See the thread here:

Thanks. I had a look. There is indeed a cross zoom blur transition, but I did not see any dissolve blur. (This is example of dissolve blur: https://youtu.be/7yf5xqTBCv8?t=107)

Hi @ed_welch, A few past threads on this forum come to mind:

Making a ZOOM motion blur is easier than a sideways motion blur transition. Hope these threads help.

Unfortunately, none of them are really the same as the effect that I linked to. I guess I’ll just have to make do with what’s there.
