This open source browser extension allows you to view the Async TI4 map in traditional portrait or PC monitor friendly landscape.
Step 3: Unzip the download and put the folder somewhere you won't delete it
Step 6: Select the folder you just unzipped
- In the address bar, enter about:debugging#/runtime/this-firefox.
- Click “Load Temporary Add-on” and select your manifest.json file.
In the top left corner of your browser during Async TI4 you will see a button "Switch Orientation" and a slider "Split %"
The button toggles between portrait and landscape layout. The slider adjusts the split point where the map horizontally meets the game overview. Adjust this slider to match your game (the preference is saved so you only need to do it once)
