I have just started using Bookends and compliments, wonderful program!
I wonder about one thing, it is more a suggestion. One thing i have missed in all bibliographic software i have seen sofar is the ability to label records in a list view, to assign a color to them for example. This can be useful to mark those references (articles/books) that you already own/ have read or whatever. A way to visualize some info on your material. I know you can also add a remark in a notes field but this is not the same.
Is this perhaps something under consideration? A usefull suggestion? I am doing a PhD and for me it would be very practical.
There is no color-coding or references at this time. It gets complicated rather quickly (you want arbitrary coloring, others have asked for colored hits, etc.). I may implement something in the future, but no doubt it won't satisfy all of those who want some kind of coloring...
