My Gnome applications menu currently has 5 pages. I scroll mouse wheel to navigate pages. As seen below, I ve hid several apps with the app hider extension yet the other icons were not moved forward. The result is inefficient. It should actually be 3 pages instead of 5 if I could remove the blank spaces.
Problem solved. I should have tried the obvious. I clicked and held icon, and dragged it to the left, It showed the previous page. It then changed to the previous page, and I released the icon. It populated.
I found a way to remove all the clutter earlier today. Im onmy phone so I cant get name of extension but it lets one make folders in the a menu. So many apps I never use will go in a folder. i ll make folders by app type and bring menu down to one page.
