First we'll want to deleted unnecessary campaign tabs shown below:
Use find tool to find "continue_campaign_6" line in .screen file an then collapse lines involving campaign 6, 5 and 4 like shown below and delete them :
Press find "continue_campaign_6" again and delete all lines involving campaign 6,5 and 4 further below in the file.
Now go ingame and your screen should look like this:
Tip: If you game crashes this means you have deleted too much or haven't deleted some of the lines I mentioned and the engine is now looking for non-existing lines in file.
As you can see we still have lock signs left behind. To get read of them find the "locked_campaign" lines related to campaign 6,5 and 4 colapse them just before "type_button" or "art guide" lines and delete them all:
Next you'll want to remove operations buttons and lock too. Find and delete lines related to Operations button and lock which are shown below.
Go in-game and your screen should look something like this now:
We can see we still have Operations background tab left behind and also that all the buttons are on opposite side of the screen. First take care of Operation back tab - these back tabs are called nav_bars in this file.
Here is the list of nav_bars (since they're not arranged by logical order):
1 - campaign
2 - operations
3 - skirmish
4 - options
5 - exit
6 - tutorial
7 - multiplayer
So find and delete Nav_bar_2 for operations (note: nav bar 7 for multiplayer is shown below):
"flipVertical = true,
flipHorizontal = true,"
line to all other nav tabs just after "type = Graphic" line like shown below except for nav_tab 1 to make them look like Campaign background bar.
Go in-game and your should lok like this now:
After that change the positions of nav_bars like shown below:
and your screen should now look like this in-game:
You can see that your text still hasn't moved so go and change their position coordinates like this:
You also may have noticed that exit back tab doesn't look like the rest at the end of the screen so you'll need to change it's size and positions again to make it look more like original (without the need to tamper with actual picture file):
We're almost done, go in-game and you should see this:
As you can see the text that appears when hovering over tabs isn't synch with our current screen layout so you'll need to fix it by changing following parameters with the file:
That's all folks! You've done it! I hope this guide has been helpful to you.
