These both sound/look like "synchronizers" or "transfer agents". Synchornizing could have uses, when not in the office/home and with two or more computers, not my need. Transferring is un-needed, also, since URLMP automatically bookmarks from any browser and makes them available to any app ( not just a browser ).
I suppose sorting bookmarks may be useful, but that's not how I organize them. I have 9 main divisions/folders with as many as 4 sub-divisions in some, plus emails and a 'catch-all'. And inside each division, I have things divided into different categories within that folder. Thus, alphabetizing would completely destroy my setup!
I put a bookmark in the list where I want it, period.
Verifying bookmarks is also available in URLMP. It just works for me and any app I want to access a bookmark from.
Unfortunately, I get no commission!
But it's not for everyone, some people even use Word for text processing!
