I am doing a medium size project, and one problem I have come across is that when reworking a part done with PartDesign, in which datum planes and lines where used attached to a master sketch, the datum planes and lines eventually lost the link (probably licit because of the rework), but nevertheless stayed in place. The rework should cause these datums to move about 1 mm and it was not very much evident that they were no longer linked, until I made the master sketch visible and set the right view.
I do not know if this is something relevant, so my question.
I have just hacked away a half working implementation that looks like this:

So basically, datums could get an overlay status icon somewhere (now is bottom left). The ones that are attached would get the greenish thingy (I thought it was a weight when I made the text pixmap, but it is not clear at all) and ones that are not attached the yellow thingy (was supposed to be a yellow balloon, not my best art, not that I can do art anyway). Practical implementation says that it should be something that can be distinguished by shape, because datums are generally not visible and a greyed out icon makes them look the same.
Well, this is just to ask the question, does this make any sense? Any follow up ideas?
