It is irrevocable that Mathworks is committed to the new desktop going forward for good or bad..
That said, submit complaints and functionality requests officially at <Product Support Page> in order for there to be any chance at all of them making changes in appearance and/or functionality. Since the Answers forum isn't an official support channel, complaints/suggestions posted here may not be seen by Mathworks stafff and so not at all certain would ever get into the enhancement list otherwise.
It's obvious that having the saved library to recall is a far more useful feature than having to manually recreate every time as well as haing to go to different places to make all the changes. One hopes that these kinds of oversights are only a temporary aberration in making the transition before it was really complete, but it unfortunately appears that the desktop was designed more for appearnce than functionality; or at least with only a very limited viewpoint of functionality from the developers' viewpoint rather than from a community-wide design/feedback process. ($0.02, imo, ymmv, etc., etc., ...)
The workarounds I would see if this does come to pass before corrected in the ui version would be
- Create an m-file for each of your saved configurations that can apply to the figure that does the stuff needed, or
- Create a set of figure-specific default setup options for the figure that can be set before creating a figure of the given target. This isn't nearly as flexible to be able to export the same figure multiple ways, of course.
What's worse than just "going to be" is from the release notes one culls
"The printpreview, printdlg, and exportsetupdlg functions will be removed in a future release. If you call printpreview or printdlg, MATLAB issues a warning and runs the new uiprintdlg (R2025a) function instead. If you call exportsetupdlg, MATLAB issues a warning and runs the new uiexportdlg (R2025a) function instead."
"To simplify the interfaces, the new dialog boxes do not include options for customizing fonts, line width, or tick values, or for setting the renderer. To control the appearance of a figure that you want to print or export, set properties of the figure and the objects in the figure before opening the dialog box."
That's simply rude!.
