Hi Rob Mer. Thank you for your comment. The function to collapse the tools pane has indeed existed for some time. However, that is not what this post is requesting.

When collapsed, the tools pane still exists as a narrow bar with a single triangle in it, to the right of the scrollbar. This means that clicking on the scrollbar is harder than it needs to be because it requires precise positioning of the mouse.

Hence this post requests an alternative, easier-to-use design, e.g. a button to open the tools pane rather than a bar to the right of the scrollbar.

Please note that inside current 1st Top Idea 'Permanently Close tools pane' <https://acrobat.uservoice.com/forums/926812-acrobat-reader-for-windows-and-mac/suggestions/46550761-permanently-close-tools-pane> I already added 2 comments to confirm that inside Preferences -> Documents a new option 'Remember last state of the All tools pane when opening documents' indeed exists in Acrobat Reader DC MUI v24.005.20320 (December 2024) and even in previous version v24.002.20687 (April 2024) to avoid Tools pane to always show itself opened while simply running Acrobat Reader or opening a .PDF with it, so enabling such option (obviously after upgrading to Acrobat Reader DC) will probably be best option to avoid Tools pane to always open itself by default and to let it always remain hidden until a user really need it to show via using its [Shift]+[F4] keyboard shortcut that let it appear from left side of Adobe Reader
window (please also note that I'm currently using it with its 'new Acrobat Reader' interface features already Enabled but if needed they can be disabled via Menu -> 'Disable new Acrobat Reader' to then get back to standard UI, for more details just see 'Introducing the new Acrobat experience' <https://helpx.adobe.com/acrobat/using/new-acrobat-experience.html>).

This is a ridiculous issue, I can't believe that this idea has not been implemented in the 3 years that this has been here. Please make add the functionality to hide or remove the All Tool menu from the Home view permanently upon launch of the application.

infuriating ugghhhh

This must have been designed by someone that doesn't use scrollbars. It's very easy to fix, just look at how in Gmail the side panel can be hidden and a small tab is left at the bottom to restore it instead of a full height bar.

Found this online post, can us this workaround.

"Okay, seems I've stumbled upon an ugly workaround but it works for me. I'm using Windows 8.1. Go to the install directory, i.e." C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroApp\ENU". Create a new subfolder (I used "Disabled"). Move 3 files from the "ENU" folder into the new "Disabled" folder: AppCenter_R.aapp & Home.aapp & Viewer.aapp. Open a PDF and no more Tool Pane! I originally moved just the "Viewer" file but if you clicked on "Home" or "Tools" on the toolbar you couldn't go back to the "Document." Moving all 3 files takes care of that issue. Like a lot of people I don't and won't ever use any of the tools. I just want a reader."

How many years has this request been made? It is not that difficult to change the codes to completely hide the Right Tool Pane. This feedback forum seems pretty useless. 2021-01-14
