Help me! I broke it!

Yes, I’m a massive noob! I was looking for the Add Modifier/Bevel button (still haven’t found it) and somehow managed to resize a menu bar. Then I tried to fix it and it made it worse… and so on! I normally just keep fiddling with things until I find a solution, but everything I do seems to worsen the problem. I now have several copies of toolbars taking over the screen! How do I go back to original menu settings without deleting the modelling work I’ve done? I tried saving it and reopening Blender, but the menu settings have saved along with the model! Attached is a picture of the mess I made. :frowning:

You’ve split the window into two. Right mouse click on a window border and select Join to join two adjacent windows together.

Ah okay - thank you!
