This now has merge conflicts as I merged some other PRs.

One problem with the button arrangement that the location of the close button is platform dependent. I assume you didn't implement that yet. To avoid having to put the close on the left/right depending on the platform (there's code in the game to detect that for the custom confirmation dialogs if I remember right) the miches button could be placed above the close button with some space between them.

[PollastreGH]

Sorry, could you elaborate on the location of the close button being platform dependent? I'm not sure I follow

[hhyyrylainen]

The position of the cancel button in a popup depends on whether you are using Windows or Linux. Here's our code where that is handled:

Thrive/src/gui_common/dialogs/CustomConfirmationDialog.cs

Line 118 in 578caae

if (DisplayServer.GetSwapCancelOk() && !Engine.IsEditorHint())

So if you want to keep the close and miches button on the same line, they should follow the platform dependent convention of which one of them is on the right side.

[PollastreGH]

I was not aware of that, thank you very much for letting me know.

[hhyyrylainen]

As part of a tutorial overhaul, I'll increase the height of the prediction popup slightly. This will close the related issue, but if you want you can continue working on this PR.
