modified reader icons

[Overengined]

I modified the reader Icons to add a little bookmark to them.
I also modified a bit the center of the books to make it look less "weird".
I think it looks nicer.

I'm not really excited about this change, the bookmarks are weird.

[Overengined]

OK :/
Well, I can remove them and jut keep the changes I made to the center of the books.
Would that be good ?

[Lauryy06]

Like this ?

Sorry but I also find it weird...

[Overengined]

Well, obviously not exactly like this because now that the bookmarks are gone, I shall adjust the colors.

I'll be honest, I prefer the current icons.
