As I mentioned before:

oops, sorry.. read too fast.

If they would have variable height this wouldn't work, instead I'd try to keep track of the height and y position with a [value] object.
Deleting one instance would have to redraw the whole GOP, which is a bit ugly but would work.
Did you manage to delete in your aproach?
I see, thanks a lot for the explanation.
Yes so far I managed to build GOP audio chains with messages, give a specific ID, loadbang every abstraction, select with a click an abstraction (in running mode and avoiding multiple selection) and delete it. Then the chain is recomposed and all the other abstractions move back to not leave the empty space of the previously deleted one (kind of Ableton-boooo effects rack).
On ubuntu with Pd-ext 42.5 GOP redrawing works like a charm.
Now I have 2 main problems I'm trying to solve:
1_ I want to be able to insert a new abstraction in a random position into the chain (i.e. not only in the end)
2_I want to be able to use whatever abstraction, with different dimensions (although it won't be that good for a usable appealing interface, but I prefer to do it in order to allow other people to easily use their abstractions)
That's why I started using iemguts (so glad it has been included in Pd-ext). I don't think it's going to be too difficult since I'll have to use the same methods with light modifications, but what I actually miss is a clean way to incapsulate this methods in high-level abstractions, as you have cleverly done.
cheers,
