The comment tool was very important for me when reading and annotating texts using the mobile app and the Google app, now it is virtually a nightmare to try to include a comment on any of the apps. In the mobile app, you have to click on "Comment" option in the menu, then select a page to insert the comment, and then select an area to put the comment. In the Google app, you have to activate the "Comment" option for each time that you want to highlight the text and include a comment. The process is very annoying in both cases, I saw that there are numerous complaints on the automatic activation of the "Comment" menu when people just want to highlight something, I guess you guys could create separate functions, instead of eliminating one function when somebody complaints about a feature...
