Yes.  One of the good (and bad) things about BookMacster is that it is three apps in one.  If you look at the wrong set of features, you might think it's the wrong app.

We mitigate this by describing three Usage Styles…

• Usage Style 1   Keep Safari bookmarks alphabetized
• Usage Style 2   Keep browsers' internal bookmarks in sync with each other
• Usage Style 3   Keep bookmarks in one central store; forget browsers' internal bookmarks.

What you're describing is Usage Style 3.  You can get the bookmarks out of your old bookmarks manager by either exporting to an .xbel file, or exporting to a the internal bookmarks of a web browser.  Create an empty Bookmarkshelf document with no Clients.  BookMacster can import those by clicking in the menu: File ▸ Import from one Client.  (Not really a Client in your case, but it works the same.)

As far as 2000 bookmarks and 5 levels deep, that's about average for a serious bookmarker.  No problem.
