I got this cooking up right now, it's actually a near perfect introduction to the code base, I don't know how to update the gui however, would need a tad bit of help for that.

On the one hand, you practically took this idea of ​​mine from January #328.
On the other hand, I will finally get spawnpoints with the updates, I'm glad you reminded them.

This feature has been implemented now! You can now set a custom spawn position using the interactive marker system. The spawn point selection is available in the GUI in the next release, which will come soon. Thanks for the suggestion - it's a really useful addition! :)
