I too am migrating from URLMP and BookMacster looks like a good replacement. (I like the multi-user function, and the sync through cloud.) There is a URLMP user forum with a small number of users who are all waiting with anxiety and frustration for a replacement - which has been promised but to date really looks like vaporware.

BookMacster does not move things around unless you tell it to.  Structure is hierarchical with unlimited levels.  As far as messing with, I don't think so but possibly I don't understand, because that would be quite odd behavior for any app to do that.  You might want to give an example.

At this time, the only way to sync from URL Manager Pro would be to export to a web browser and then import from the browser.  This would likely not be seamless, although using Camino or Firefox might come very close.  One of the things we need to do real soon is implement XBEL or HTML import/export capability.  It should be a fairly easy task, and would enable people to import XBEL or HTML files exported by URL Manager Pro.  Check back here in a few days.  I wonder how many people are still using URL Manager Pro, though.  Last time I checked, URL Manager Pro was not supporting Google Chrome and not even Firefox 3.  Did they ever fix that?

Yes, unlike those guys who sync your bookmarks through their server in the cloud, BookMacster is like URL Manager Pro in that it syncs local browsers locally.  It does not go through the cloud unless you're syncing different Macs in different locations.  If you want to always initiate syncs manually, just don't create any Agents.
