I'll soon be releasing my first Mac OS X native application, MassReplaceIt. Basically it does a find and replace on either the contents or filenames of a list of files you give it, so that you don't have to open them individually (screenshot below). It will be released as freeware. I developed the application in Panther, however it should also work in Jaguar, although I'm not entirely sure since I don't have access to a machine with Jaguar installed. I'm interested in people's feedback on it. In particular, possible interface improvements and bug reports. If anyone tests it in Jaguar, I'd be interested to know if there are any problems with that. Help is available from the Help menu if required. The beta version is available here (120 KB). Thanks for you help.
