Arrogant cunts at Tapbots. Theres a new version of Tweetbot (3) for the Mac. Brings back dark mode & changes lots of things.

But it's not apparent how to add more columns. Arrogant arseholes assume you know how to do it.

Various unhelpful websites mention dragging the "column circle" to the right to add columns & back to the left to reduce the number of them.
But at no stage does anyone explain what & WHERE this fucking column circle actually is.

Turns out it's HIDDEN, only becoming visible when one hovers the cursor over a tiny piece of screen real estate in the bottom right corner of the window.
And if you should happen to be in Dark mode, the way to reposition these columns is almost invisible, too. It is more obvious in Light mode but it's still HIDDEN.

HOW THE FUCK IS A NEW USER TO KNOW WHERE THESE CONTROLS ARE LOCATED?
