I just committed a first fix that fixes a few issues. Currently, a bug is still pending: a crash can happen if a undo command uses a removed item. About vais, that are multilayers items, blind/ buried vias and especially micro vias are a tricky case. Currently they are removed (due to a small bug in code) if they start on a removed layer. But the actual problem is: Should we remove them if they are still living on existing layers? And if not should we modify the layer pair. Micro vias for instance are blind vias connecting 2 adjacent layers, so we could modify easily the layer pair without removing them. -- Jean-Pierre CHARRAS _______________________________________________ Mailing list: https://launchpad.net/~kicad-developers Post to : kicad-developers@lists.launchpad.net Unsubscribe : https://launchpad.net/~kicad-developers More help : https://help.launchpad.net/ListHelp
