Just a personal preference from my UX POV. Enhancements over features. Examples (last time I dug in): The mobile icons acquired the Collapse footer. That was prime real estate. Some Active Callbacks seem finicky at times. No core rgba color control. Multi-click panels. No panel/section cursor click-backs (clicking Static Front Page, mouse has to go all the way back to top). Depending on a theme's nav walker, clicking through Live Preview links can be sluggish and the beforeSend or refresh indicator gives awkward state indication. Sometimes Change theme panel, while in scroll gets stuck and can't go back up. Sidebar is too wide. GUI readability. Etc. BUT, these are all enhancements 3rd-Party Developers have been able to improve or master.
