Naturally, I use adobe acrobat reader mainly for reading pdfs. However, with the new update, I find the big bright colourful button in the top right corner very distracting. Acrobat reader is designed mainly for viewing pdfs, so it would make sense for it to have a streamline user interface that puts emphasis on the pdf being viewed. While that is the strategy adopted by most pdf viewers, it seems like acrobat reader took a turn for the worst and decided to sacrifice user interface in order to force AI features that nobody asked for into their users workflow.
Please, if you are going to keep the AI features in a pdf reader, make the button smaller. It is just in the way.
