Hello,

Please consider providing a means to remove the tab for the default group and the "add group" options in the upper left. This would effectively be a "one group only" mode. Thanks.

It would be great if the addon icon provided some kind of visual indicator that showed whether the current local bookmarks were synced with the server.  Basically, this is a clean/dirty indicator that shows whether a synchronization is needed. It would go to dirty any time a local bookmark is modified, added or deleted, bringing the local system out of sync with the server. It is a visual reminder that the local system needs to be synced to save the changes to the server.  You could, I suppose, make this optional for people who choose to enable the autosync feature. For those who are not using autosync, such an indicator would be very helpful.

I am categorizing this as Eversync - Chrome, but the request applies to all the browsers, and really to any version that syncs with a server.

do not sync correctly

During the installation of Eversync for IE, Malwarebytes Premium detects the software as a  potentially unwanted program (PUP). I am able to add it as an exception. My concern is why is it being identified as that. 

There is no extension like Xmarks (when it worked well).  It had a user-friendly web UI.  I could expand the different backups and see their content.  I could choose a backup to make it the current syncing bookmark set.  I could remove backups.  I could view the contents of the current set.  Many other options. 

I would say that in terms of features, ES sync/backup is somewhere between the built-in Firefox sync and Xmarks. 

Right now I actually prefer the built-in Firefox sync because it's MUCH faster than ES sync.  For example, after the initial sync, then pressing the sync icon makes it spin for maybe 4-5 seconds tops). 

The one thing I use in ES is the auto-backup feature.  Too bad there is no setting for the time period between backups (I think it's 15 min and it cannot be changed), but it's better than the built-in Firefox backup, which only backs up bookmarks once a day.  So that's the only reason I'm using ES right now. 

This is an opportunity for extensions like ES to fill the gap that Xmarks left, but it would require a lot of work by the team.  Hopefully this thread will provide more ideas for improvement. 

Good luck!
