If you would like to see additional or modified functionality in a future release of iPadOS, this would be the most appropriate channel through which to make your request.
iPadOS 26 has introduced new multitasking capabilities and controls - with, optionally, Apps appearing within their own windows instead of being full-screen or appearing in side-by-side split screen. To better understand the changes, I recommend that you start with the video introduction here - and then read the remaining explanations:
Multitask on iPad with iPadOS 26 - Apple Support
iPadOS multitasking has received a significant makeover from that to which you may be accustomed in iPadOS 18.x and earlier - and may take a little time to learn and adjust your workflows. You would be well advised to review the official iPadOS User Guide and the many available online tutorials (such as YouTube) to become better acquainted with the new multitasking interface and associated gestures and controls.

The three-dot multitasking button with which you are no doubt familiar from earlier versions of iPadOS has been replaced with the traffic-light button to access and control the revised window-based User Interface.
Tapping the traffic-light multitasking button expands the control - whereas touch-and-hold of the button offers the option of arranging open windows side-by-side, as a tripple, arranged into a quad - or slide-over views.
If you dislike the windowed environment, you can switch to using the basic Full-Screen App mode - but this disables all multitasking capabilities and hide the traffic-light controls; you will not be able to use split screen or slide-over modes with which you are likely familiar:
Settings > Multitasking & Gestures - select Full Screen Apps
