As mentioned in the open discussion I think this is a great addition to phpgedview.
I have used the search and replace a fair bit over the last couple of days.
One issue which is very strange is that it will not search on SIMPSON. I tried to shorten the search term and it just hangs on SIM or any thing longer (ie SIMP) It will search on SI. I have about 39 SIMPSONS in the data base so it should find them.
This is the only word that appears to be giving an issue
