Currently the iPhone or iOS app for adobe acrobat(reader or otherwise) nests bookmarks down two levels of clicks. First you have to click the ‘•••’ then you have to click “Bookmarks.” Then you have your first level of bookmarks. And at times each bookmark will have subsequent bookmarks because not all pdf are small. Some have multiple chapters or subjects and thus nested organization is required.

Please consider a feature to add to preferences to show bookmarks or other features on bottom bar or let me view bookmarks while I view the doc. Because you may not click the correct bookmark the first time. Bookmarks should allow easier browsing. An older version had it pop out from the left. This was superior because the UX design allowed less tedious actions to get to it.

OR a gesture to swipe open bookmarks or a custom definable action such as choosing a highlighter or other feature available on reader and pro.
