This is not a bug, neither exactly a wish. I wouldn't know in which forum to post it. So do it here.
I find the bookmarking behaviour, well, a bit strange. I'm using it now for language studying. And bookmarking becomes very useful sinceit allows to bookmark the beginning of a reading and listen to it again and again.
But here comes the strange thing: if I double click in the bookmark, I would expect MB to go to bookmark. But it doesn't behave this way: it just keeps playing from the same point I stopped it. So I double click the bookmark to go back to the bookmarked beginning... and it doesn't! Wouldn't be more logic to go to the bookmark when you click in the bookmark???
And a second thought: when you bookmark, you bookmark the beginning, so the second time you bookmark MB thinks that you're stablishing the end of the previous bookmark... if you want just to bookmark a point to play from, but you don't want to create a end of the loop (just the bookmark so you can go back to it), but to bookmark another point to start from in the audio file, it becomes a bit confusing...
