Tabulations for webpage widget
I suggest Tabulations for webpage widget as some links are made to open a tab in the browser and that helps.
Example : if you know managewp, if manages multiple wordpress websites and clicking on a website open a new tab to access admin area.
In freeter the admin website will open in place and that does not help.
I don't care about the solution, if you don't like tab, it could be a lateral panel or whatever but something is needed
