This involve interface modding.
first, type "guibounds" inside your console, you might see that there are red frames all around, they highlight the layers and components that make up the ui.
hover your mouse over the new debug window, and I suspect you see it showing the components that construct the ui and pointing to a file inside the interface folder, named "console.gui" (just making a guess here I don't have 3.10 yet because there are too many bugs
I suspect that you just want to edit the position of the debug window and don't want to mess it up, so
be sure to make a extra backup of the ui before you edit it!
every ui in Stellaris are made layer by layer. Every UI begins with a guiType, which will contain all components. the next is containerWindowType, which literally acts as a container that contains other components, stacking to make the ui. the order of the layers stacking are based on the sequence of the code, also the indentations too.
I suspect a new containerWindowType has been created to contain the new debug window parallel to the old console. now you have too options to locate where does the code of the ui locate. 1. look inside the console.gui, and scroll down to find the least indented containerWindowType other than the original console. how do you differentiate? look at the name element. The other way is the "guibounds" command. hover you mouse to the edge of the ui until there is one bracket left, and that is your base container. I suspect that it shows the line number of the code, go to your file and press ctrl+G and type in the line number. (again, I didn't update, so I'm guessing
finally, you can edit the location of the window, edit the position element, which probably looks like this “position = { x = @random_value y = @random_value }”. The @xxx are just a global variable created before, you can probably find it at the beginning of the file. if you can't, use ctrl+F. after you made the edit, use "reload_gui" command to reload your ui without reloading the game. "debugtooltip" also work, just ctrl+alt+right click the ui to open up a interface that you can reload the gui with.
"reload console.gui" doesn't work on my computer, but maybe it work on yours.
hope this is what you need.
