All Mangas Reader

I was wondering for the next update you coul put a different colour for the manga which are completed, and those which we just reached the last current chapter,
for example a light green when the manga is completed and no more chapters are to be expected, and the same blue for those still in activity
After they could either be rearranged just like the 3rd image, or if it's too much work, simply left as in the second.

If it is possible, we could think about maybe implementing it for works that are on "hold" or "hiatus"
Or we could even think about coloring active manga with a darker blue for those who are on a irregular basis or manga who hasn't had an update for over a month would slightly go toward a gray colori

how would the extension know if a manga is completed or on hiatus?

the only method I can think for doing this is creating a database with a list of completed/suspended mangas, but that's a lot of work

well, most of the time when we reach the last chapter of a mange you have a message that says that it's the last chapter (like onemanga did) and some site (I don't know if all do) say the status of the manga, that's why I thought about it.

if it's not fesable, maybe then he could just allow us to change the color, then we would be able to change the colors ourselves.

Or for example, it could be done by the community. When someone finishes a manga he would tick a box which would say that the manga is over, and when a certain number of votes are reached, it would automatically turn green for the rest of the community when they reach the chapter.

well, if it's on hold or hiatus, and you don't want it to be blue, then you can turn on the "do not follow this manga" option, and make it gray, can't you?

In other words, we already have an option like this... Just press the little arrow by any of your manga, and press "Stop following updates"
