Why not give us the option to set it up how we want it? That way those that like the old broken up way can do that while those of us that prefer it all in one place and love the new setup with the buttons on the side to easily access everything can do that.
It is neither better, nor is it more standardized, particularly among apps for which "Pro" is more than a marketing gimmick, whether it appears in the name of the app or not.
If nothing else, even on single monitor setups not being able to detach panels from the workspace windows & place them wherever on the screen a user wants wastes lots of screen space with multiple copies of the same UI elements in each window. Likewise, since some tools have lots of settings while others do not, with all of them sharing the same screen space on the right, there often is a lot of useless empty space on the right that better could be devoted to the document window.
Besides, it really isn't a "single window" UI anyway: Shapes, Colors, Gradients, & Document Info all appear in their own windows.
Imagine you have desk set up just the way you like it. Everything you use is easily accessible, you can see what you need right away. Then you come into work one morning and somebody has placed all your tools into little boxes that are glued to your desktop and the lids open inward obstructing the view of your project. Also, you have to open and close the box each time you want to use a tool.
PLEASE ADD DETACHABLE PALETTES!!
The older version of Pixelmator has it, there was no reason to take that away. I've stopped using Pixelmator Pro because it's such a hassle dealing with the single screen.
Consider this another vote for detachable/floating palettes in Pixelmator Pro!
I am super jammed on my tiny screen now.
Just bought Pixelmator Pro today and it's astounding how much screen real estate is wasted by the single window design irrespective of dual displays. I work with a 13 laptop on the go and the new UI either puts what I'm working on in a porthole or I have to constantly show and hide sidebars.
Enormous UX regression. Please reconsider.
I've also worked on a dual monitor set-up (PC-based, not Pixelmator) and tried putting pallettes on the second screen. I found it too long a mouse-journey and ended up putting my main app and all pallettes (if it had any) on the primary screen and *everything* else onto the second. This gave me a one screen with emails, notes, phone messages and a web browser and the other screen with a single focus on what I was actualy working on.
I guess the message here is that we all work differently. While I found it impractical to put pallettes on a second monitor I understand that someone else might find that a good way of working. While I found floating palettes always got in the way on a small screen I understand that others might prefer them to sidebars.
As it's people who want to change things that are usually the most vocal on a subject and many of those are saying "this is wrong, please fix it," rather than, "I'd like it to work differently, for me," I'd like to add my voice to the conversation. That voice says, "I like tools in sidebars. I always know where they are. I like the ability to show and hide them with a keystroke if I am short on screen space. And I would love it if the remaining palettes could make it into sidebars too."
In addition, we would like to make Pixelmator Pro more dual display-friendly. That's not to say we want to completely change the existing UI design but there are certain features we could add that would make it possible to use two displays more efficiently.
