Description
when reading through an item, it may refer via a link to another website that you wish to subscribe. liferea makes it easy to subscribe to this new feed by offering a 'Subscribe' menu option by right clicking on the link. Unfortunately, liferea switches to the new feed's item list when processing and populating the new feed. It would be convenient if the population of this new feed happened in a new tab. This would preserve the context you currently are in with the current item feed's to-be-read list.
I often find that I am reading through items or open an item in a new tab, and want to subscribe to a new feed. I defer subscribing to the new feed until I am finished reading all the current new items because I know I'll lose my place (context).
Note there may be difficulty with maintaining the state of the feed list pane when opening a feed in a new pane. The feed list pane would have to change to match the current tab's state.
A side effect of this feature would allow user to edit or read a second feed list in a new tab.
