The feature that pops up little previews of links is very useful. But it is not useful when you open such a link in a new TAB in the browser and upon closing said TAB again, that little window is still there and blocks the view to underlying text. You have to find a new link to hover the mouse cursor over to be able to close it.
I usually get so P. O. that I turn that feature off altogether. I guess this was not the intention with its birth. Or perhaps it was? I don't know.
I guess you could say I find it too obtrusive and far too persistent for my taste.
Perhaps a time delay until it is shown, and a timeout when it is automatically closed? If there is, that's far too short in the beginning (showing) and far too long at the end (closing).
Perhaps I'm the only one finding this a very odd behavior. Using Manjaro Linux, Firefox browser. If that matters.
I will probably not be back here, unless I stumble on the topic somehow. Just thought I'd vent my dissatisfaction with this otherwise nice feature.
