On 18 Mar 2017, I tried the 7+TaskbarTweak no_width_limit option  in my Win7. Worked even after reboot.

Important to small screens.

— (tested on 30 Nov 2020) Use small taskbar buttons to further reduce the width
search “taskbar settings” -> UseSmallTaskbarButtons

— Installation error: On 30 Nov 2020, I hit a problem re-installing 7tt on my win10 A299. Installer was unable to write to a ProgramFilesX86\….

Not a disk space problem. Also the account was the default admin account.

Solution: I created c:\programPortable and installed into a subfolder.
