Yes it would be lovely.

On closer inspection of my mod it does still "kinda" work.  it still tries
to display the controls but it's not able to deal with any designer set
values anymore so all i get is the generic default control as seen in the
attached image the designer view on the left and the runtime look on the
right.

So even my mod would not help Jorge here.
It worked fine a couple of months ago but Ben changed something and now
it's limited. But still better than just a box

It truly does give problems when you are working on the control though. as
the IDE has pre-loaded the control code any changes you make confuse things
(like changing property names). you have to do a lot of "compiling the
control, then shutting down the IDE and restarting it to reload the
controls changes"
Point being it's not as simple and straight cut as you would think to see
your custom control properly in the designer, especially if you are working
on it. there's a whole load of error checking and control reloading going
to be needed.
