[Feature request] Toolbar popup

[mario98]

Would be really cool if there were a feed popup when clicking on the toolbar button, similar to Feedbro and Feeder. (Where I like the popup by Feeder even better because it can show old feeds in the popup and also groups feeds by website, unlike Feedbro which just shows recent feeds without any grouping).

Feeder is actually a really cool addon, so sad it's commercial, otherwise I would just use Feeder and not file this feature request here. With commercial addons there is a high risk that the addon is spying on you like most of the other commercial addons. Remeber WoT, ProxTube etc. pp.? Terrible. I'd never use commercial addons, instead I always try to support and push open source free alternatives.
