I've been using
Brother's Keeper for several years and it is constantly being developed by its author. The
BK Support forum is very good and quite active.
If there's a feature that isn't already part of the application and you think it's a good idea to have it, the author will consider it and, if appropriate, will develop the solution and it will appear in a later version.
It is shareware, but once you pay a relatively small fee, extra features are opened. Having said that, if you just want to try it out, and not register it, it is probably the best featured (and NOT time limited) application of its type out there.
