Well, there are two issues.  The first issue is just exporting; the second is syncing.

The answer is that both are issues for any browser.

In Firefox and Chrome, we deal with the first issue by using browser extensions when the browser is running, and deal with the second issue by not allowing Chrome Sync or Firefox Sync to be used when BookMacster is also syncing via Dropbox or other online file syncing service.

The issues with Roccat would be the same.

I see well I don't know enough about it i'll leave that to you guys   

I believe it just sends the plist data to the cloud, and obviously sends it back if you restore.

I think (i'm not the most computer literate person in the world so not 100%)

May I suggest you try the browser Roccat (it's what I use) they have a feature called RClouds which backs up your open tabs (also bookmarks and history and settings) to there RClouds system. you can then reset roccat so it's completely empty and can restore those tabs etc... whenever you like, it's also a versioning of backups so you can back up various sets of tabs and restore as and when you wish.

The only down side is the Bookmacster doesn't support it (which is actually why I have created an account as I want to request it's support).

Recent versions of Safari have a menu item entitled, for example, Add Bookmarks for these 15 tabs (or however many tabs you have open).  Firefox has a similar item, Bookmark All Tabs.

I presume that you are adding bookmarks to BookMacster directly, using one of BookMacster's bookmarking tools…

• Status Menulet (BookMacster icon in menu bar)
• BookMacster's Dock Menu
• BookMacster's Add Quickly and Add & Inspect menu items in Firefox
• BookMacster's toolbar button in Google Chrome
• the BookMacsterize bookmarklet

You would like to be able to add all open tabs directly to your BookMacster Bookmarkshelf using some of these methods.  Am I correct?

If so, the answer is that none of BookMacster's direct-bookmarking methods have that feature.  You must activate the tabs one at a time, and then click the appropriate tool to add each one.

Personally, I've never wanted to Bookmark All Tabs, but I suppose that since both Apple and Mozilla have added this feature, you're not alone.  Would you like us to add that feature?  Which of the above tools do you use?

This feature would add more menu items and modifier-key options to BookMacster's various bookmarking tools.  It should be technically possible to get the tabs from Safari, Firefox, and Chrome, at least.
