Feature request: Easy adding of text/ text-bubble "anywhere"

Good idea that I have already had but not the time to work on. :-(

a statc bubble can be easily added:
1) take gimp with a png having a multiple (for acuity reasons) of your frame's resolution
2) ---> color -> color to alfa->translucid to your entire sheed
3) put your frame in a layer (to see where to paste your bubble)
4) paste your bubble ( for example drawn, scanned and scaled right : in another gimp window) onto layer with translucid background
5) save the layer of bubble with png format
6) use this png in a track just above your video giving it the duration which is convinient (don't bother about the multiple resolution of your png, it will be formatted right by openshot)

tadaaa done

would be fine to be able to move this bubble with a function of openshot .... or whatsoever program (advise how to do are welcome)

yes, thanks for the "tadaa-done" :) The idea of this sequest was it's two first words "Easy adding....." :)
Now imagine I wish to add 10-20 bubbles pinpointing different features in a video ..

This is color bubble. And she has been created with Inkscape, really great sofware,even I love Gimp, my first open source software.

@ed
I've got created there are a while, several titles with Gimp but I have had a problem with the text in Openshot.

Hum I am not sure that we could do that even that's right that will be nice/cool. But like it is done with Inkscape, you could open it with and move this one everywhere you wish.
