Add missing features and modify some UI

[ooHAoo]

Noticed that some of the added features from the other students are missing and I believe most of them were pretty useful and they do indeed contribute to a user friendly web extension so I will be added some of those back. Also, will modify/move things around a bit (without touching the other features) to make them more user friendly.

p.s. please let me know if some of the features have been removed for a reason (though I did not see any issues created about these removed features)
