Glad you like it. I'm sorry that I didn't think about it earlier, took me only half an hour to implement...
I have a bit of a problem in single pane mode though.
I'm okay to brainstorm that subject with you. Here's my point of view...
When I've started experimenting with the single-pane mode, the first thing that I've noticed is that when you select a movie from the grid, you expect to see the movie panel appear. If you select a movie, and nothing happens, and you have to make appear the movie panel, that's frustrating and looks like a bug.
If navigating the grid with the keyboard is a great feature of the dual-pane mode, unfortunately it can't work with the single-pane mode. With the single-pane mode, you have to navigate the grid with the scrollbar or with your mouse wheel, and select a movie by clicking it. With the single-pane mode, you can't navigate the grid with your keyboard, because it'd be strange when you select a grid cell if the movie information isn't displayed.
I think things would be more intuitive if you stuck to arrow keys for grid navigation and Shift+Arrow Keys for pane navigation.
In my opinion, navigating the grids with the arrow keys doesn't make sense when you're in single-pane mode. I tried it, and it looks very weird, because as I said, when you select something, you expect it to be shown. There are other ways to navigate a grid (scrollbar, mouse wheel). Most users doesn't use the keyboard arrows at all, only the mouse, and they won't even notice.
Each mode has its pros and cons. The dual-pane mode is great to navigate with the keyboard, but it shows less information. The single-pane mode uses all the screen, but you can't navigate a grid with the arrows.
In the end, the single-pane mode is a very standard type of interface, while the dual-pane mode was a specificity of Coollector which allowed great things like the keyboard navigation. Now you have the choice: using one interface, or the other, or switching between the two. But when you use the single-pane mode, you can't expect it to have all the functionalities of the dual-pane mode
That's my conclusion. I'll be happy to hear your opinion.
