The new Info panel in V8 is fairly nice, in that it's more flexible than the old V7 version. However, I do find some problems with it.
1. It's designed to be vertical. If I make the Info panel very wide, it doesn't take advantage of the extra horizontal space at all.
2. It uses more space than is strictly necessary. It's nice that you can expand and collapse whole categories of info like Metadata and User fields, but these things become indented and take extra room. If I want the regular info (e.g. File name, File size) and some camera EXIF info, I end up devoting 3 rows of space just to show "Info", and then "Metadata" and "Camera" under that. In addition, the actual data shown is indented. The regular Info is indented by 1 "space", and EXIF data is indented by 2 "spaces".
I can think of 2 ways to handle this. One is to make the Info panel smarter, so it can show multiple columns of info when it's wide enough. The other way is to split the Info panel up into a "regular" Info panel, a Metadata Info panel, and a User Fields panel. This would (sort of) let me put the info across the bottom of the V8 main window, in a horizontal configuration.
