Hi,In case you didn't notice in the commit logs, I committed a big patch that changed quite fundamentally how the tabular inset and its dialog works. There is still a lot of room for improvement but I believe we are now in a much saner situation. This code was so broken and complicated that it was almost funny :-)
So, please hard test this dialog and try to fix remaining bugs (which is now way easier than before).
Thanks in advance, Abdel.
