Hi Eric and welcome to AmiKit Support Forum.
I don't have such an information that IBrowse is not going to be developed any longer. Yes, I remember the IOSpirit, the distributor of IBrowse, quit the Amiga market several months ago. However they also said that the future distribution as well as development and support of IBrowse will be handled directly by the IBrowse development team. You can find their website at http://www.ibrowse-dev.net/
I would also love to see more full registered programs included with AmiKit, especially those that are not available for sale nor developed anymore. However the authors of such a programs decide, not we. We cannot include registered programs into AmiKit without the permission of the appropriate authors.
But you can help! If you (personally) know someone who programmed an useful application, try to ask him about the possibility to provide us with a full version and permission to include it with AmiKit. It would be great.
