Maybe this can be changed in the settings, but I find it rather annoying that no matter what you click here - ie. the attachment, does indeed open in the same browser as the Board itself. After reading the word document, you most likely click X to close it, and then you have lost your board-session. An attachment should open in a new browser-window instead.

 

Likewise - with the board itself. When answering in a thread like I am doing now, I would like to be able to see the original post I am answering - in particular if the original post is comprehensive, I would need the original text while answering.

 

Just my thoughts....  otherwise, the board looks fine.
