NEED (!!!) a SEARCH BAR in Preferences to find the relevant parameter !!! Are you serious ???
When we have a problem in Acrobat and try to find a solution by modifying a parameter, we go to [Menu] > [Preferences...] and arrive at a panel containing thousands of parameters in dozens of subsections. We have no choice but to browse and read all the parameters one by one, hoping to find something relevant. It may take hours to go through cycles of "Change a parameter/Restart Acrobat/Check/Undo parameter change/Look for another parameter" with the risk of missing the relevant parameter! This is not a tolerable way to propose parameters when there are so many! You need to update this old method. Just look at how Google or Microsoft handle their browsers (which we now use in our company to read PDFs because of your problems and Acrobat's terrible touch screen behavior!). When accessing parameters, they first auto-select a search bar field to find the relevant one, using a real-time "typing" filter and yellow highlighter. How is it possible that you still do not propose your parameters this way? Are you serious?

You are killing your software by not improving this critical problem.

Comment : Same behavior on a smartphone when you go in "Parameters", you arrive on a "search/filter" field to quickly find the relevant parameter ! How could it be an other way ? We are no longer in 1970.
