A feature that I really would like is to be able to view, or even better edit a note from the overview page. Sometimes I want to add some remark to a game but rarely do it because imo it is buried one page too deep as you navigate away from the overview page. And if you have a note, you don't notice until you open the game page again.

My idea was that when a note is present a little icon is visible somewhere, and when you hover above it it shows the note. If you click it, you get a dialog to edit the remark. Alternative is add it to the quickedit page, as long as I don't have to leave the overview page ;-)

I assume you're referring to the Note textbox that you get when on the Collection Details page? (ex: http://www.completionator.com/Collection/Details/1) In other words, a note that's specific to a game?

When you say Overview page, do you mean the Overview tab or the Collection tab? I could definitely add it to the Quick Edit modal on the Collection tab, but I like your idea about displaying an icon so you know there's a note already. I could always display the icon, but only "fill it in" if you have a note, or something like that.

Ah sorry for the confusion. I did indeed refer to the note text on the detail page of a game, and an icon on the collection tab for the game it concerns.
Would be great if you could also show the note when you hover above the icon, but it's of course your call if that can be realized without compromising performance etc.

I added a note icon on the right-hand side. It has a green color (just like the buttons above it) when there's a note present, otherwise, it should be a dimmed out gray color. If you hover over the icon, you should get the note in a Bootstrap tooltip. You can click on the icon to get a modal where you can edit it. if you save the note, it'll refresh the row with the updated note. Let me know what you think!

Nice. I like the addition of the note icon. I'm not sure if I'll ever really use it, but it definitely makes adding notes easier.

Wow, that was fast :-)
And it works great! Thanks a lot!
