I have been using ReminderFox for a calendar based reminder list. Now that Lightning is integrated into version 60 I'm trying to configure Lightning to create a calendar based reminder list, and use it instead. Unless I set the event view to a single day I can only read two or three words of the event description (unless I double click on it), and when looking ahead I don't need the time information (which wastes a lot of screen real estate). I imported my calendar from ReminderFox, and checked tasks in "events and tasks" to get rid of the large calendar pane. I now have three vertical panes in a Tasks tab - a mini-month (useful), new tasks pane (not useful), and a vertical event pane that identifies today, tomorrow and the date in later events (exactly what I wanted). How do I get rid of the middle vertical pane? The only way I can find to get rid of it re-enables the calendar pane (wrecking the calendar based reminder list), and I can't seem to drag and drop the vertical edges to reduce the size. The mouse cursor will change from a single arrow to a horizontal double arrow when I select the edge of the vertical pane, but it won't let me drag and drop it. As a temporary workaround I closed the Tasks tab (that had the mini-month, new tasks and events) and dragged the border above "show completed tasks" in the "events and tasks" vertical pane in the main window as low as I could. That only wastes the bottom 3 lines in the vertical pane on the right. This is a reasonable replacement for what I'm used to but there really isn't enough room to have all of the data I want to see in the folder pane and the event&tasks pane at the same time. Especially since I like to read messages in a message preview pane instead of a tab/window. So I enabled the Tasks tab again. Any suggestions on how I can get rid of the middle vertical pane (new tasks) in the Tasks tab or reduce its width?
