While the first column is the channel name, I can't edit it and have to click any single channel in order to get the editable field on the right. So it would be nice if the channel name in the first column would be editable. Also a channel number column would be nice (with thw points below taken into account)
Also:
1. It would be nice when the left window (the one with the columns) would not go back to its initial state (go to top, reset columns width) when one edits anything. The way it is now, one needs to scroll and resize the columns for every edit.
2. Clicking on the column header should sort the values below (e.g. clicking on "Favorite" should order the fields below by "X")
3. Windows has a nifty functionality: when you double click on a border of a window (where the cursor changes and indicates that it can be resized), the window gets maximized in that particular direction. Could this be implemented?
