Alright,

this is something extremely simple:
Used Powerpoint for layouting and simple effects, and game-icons.net for graphics which I filled out right on their page and copy/pasted on this "map" ..
Throw in some lables, wirte some text, done.

Time and effort: 2 hours tops.

So, yeah .. making bookmarks actually can be pretty simple



Kind regards,
