I just got around to testing gog 2.0 so here is my feedback
under "Customize grid view"
*please add release date
*please add reverse release date (sort by oldest to newest instead of newest to oldest)
There should be a sort order switch for everything, because why not? If you're a completionist and go for trophies it'd be nice to sort ascending to see what games you haven't completed, and vice versa for games you have.
I know you can filter for genre and custom tags, but it'd be nice if you can just use the search bar too, it might be a little quicker.
Also, when you group games it gives you the big collections of 30 genre tags, it'd be real nice if you could just right click and collapse or expand all from a pop up menu instead of manually closing them all or a lot of scrolling.
In the Grid view I'd like to be able to show release date under the title in "Additional Data." You can group by release date, but before 2010 it goes by decades instead of individual years, which is annoying. Make a group by decade if you're going to do that.
Now that I look at it, I can put release date, critic ratings, and last played in the columns on List view, but not in Grid View.
I can do company name and installation status in grid view, but not in list view.
Grid view has game time and achievement % in the same bundle, list view has them separate.
There's no good reason for these to be limited to one over the other.
