Make the TYPO3 backend page tree and file tree container horizontally resizable again (including element/link browser dialog).
The possibility to change the width was removed in TYPO3 8. This becomes a problem in bigger installations or when your tree structure is deeper (or simply the names of your pages are a little bit longer). You would have to scroll a loooooot!
This extension adds a little bit of Javascript and CSS to allow any user to resize the page and file tree container horizontally again.
This works in the Web > Page, File > Filelist module and (new since version 1.2.0!) in the element/link browser dialog too.
The set width is then saved in the backend user preferences (uc field) as Backend.PagetreeResizable.width and for the element/link browser as Backend.PagetreeResizable.Browser.width.
If you double click on the resize handle, the container expands as wide as required for the content to fit.
It works with TYPO3 8.7 LTS, TYPO3 9.5 LTS and the upcoming TYPO3 10.2 and I tested it with recent versions of Chrome, Firefox and Internet Explorer.
