Thank you for your reply. It's very appreciated.
Please don't try to lesson the impact of this incredibly unwelcome and just incomprehensible change: it's not that the floating search field "can" get in the way. It IS in the way! Every single moment of my work day! By obscuring the names of my patients / chart ID #s / medical notes I put in OneNote page titles, this change increases the risk that I will make a patient error.
I keep OneNote minimized so I can access at the same time other required platforms/documents on my desktop to do my job, and can't / shouldn't have to enter full screen mode to "fix" this problem MS has created. That is not a solution.
Please don't "reduce this impact". Don't try to "further improve this area". Just fix the problem! Put the floating search field back where it belongs, out of the way in a menu or toolbar, and not covering part of my workspace. Problem solved. It's really that simple. Not too many "right conversations" needed. There is no scenario, with probably any software/app ever created, where an immovable, unremovable, floating search field covering the workspace is appropriate. Thanks.
