Hello there? do you want a big G-menu so you can put all your mods? then this guide is for you!
First, you need to go to your space engineers folder:
Then go to the Content/Data/Screens/ folder.
Duplicate your CubeBuilder.gsc File (backup in case ♥♥♥♥♥♥♥♥ happen):
Then, open CubeBuilder.gsc with your favorite text editor (notepad++ in that case):
Search for a section that look like this (/!\ there's two <MyObjectBuilder_GuiControlBase xsi:type="MyObjectBuilder_GuiControlGrid"> sections, search for the latter one that EXACTLY look like this, look at the column and row number, it should be 10 for columns and 6 for rows, not 10 and 1.) :
Edit the values, X and Y in the position section define the position of the grid on the screen, DisplayColumnCount and DisplayRowsCount change the number of columns and rows shown at the same time, Only Displaycolumncounts seem to affect the total number of items you can get in the menu.
Annnnnd it's done!
You can play with the values to your likings.
This tutorial explained what is done by the G-menu extension. There's no mod doing this, as the file you just modified can not be changed by a mod.
