It irritates me to no end to waste precious real estate...
For example, just look at all that white space above, to the right, and below my window...
And why am I not able to adjust the size of this popup window... I mean, I cannot even see the full names of the columns.
Also, it really annoys me that I cannot easily customize resources to show only the details we need to see, or are relevant. (at least there has been some progress with this lately, as well as a few workarounds, but still not ideal...)
