CorelDRAW should have a Maximize Work Area button and shortcut.
What about another shortcut key when pressed and hold, all bars, boxes and pallets appear temporarily (and without any changes of zoom level), and return hidden when the button released?
Adobe products do that with the <Tab> key. I've found that you need it with their products because their tool palettes take up too much space.
But it's proven to be quite annoying to have to toggle back and forth to click on one tool button.
Consider this. If you've seen the cool animated icon strips that Vista and the Mac OS's use then you could think of at least the toolbar buttons on the side doing the same thing, except they are hidden off the side.
Corel's Dockers could also be enhanced by allowing them to expand out whenever your mouse pointer hovers over the associated docker button. And collapse after leaving the opened palette for a second.
Maybe, we could still be allowed to edit when in <F9> full preview mode... just think! No clutter at all, just pure artwork space and the currently selected tool.
Magic said:toolbar buttons on the side doing the same thing, except they are hidden off the side.
That forces you to have tools on the side. But press/hold key restores bars and palettes to its state before maximizing work area, whether they were docked to the side or floating.
With press/hold key, you can move your pointer between bars and palettes (like selecting a tool from the Toolbox, and then set options from the corresponding Property Bar, then a color from a palette) without auto hide, show, hide, show…
When work area is maximized, I prefer to show tools just when I need, not when my pointer comes near or hits the screen boundaries.
But since we are talking about CorelDRAW, why not have both options; Auto-expand and press/hold key to choose between them or both of them in the same time.
By the way, here are some comments about Full-screen Preview in CorelDRAW.
