I have not ran the latest version, so bear that in mind .
Publish
Does not scale to the width of my screen 1920x1080

.
Version
There is a version in the xml, <info name="1941 Global Command Decision" version="1.285"/>
TripleA does not read the version but the app can.
TripleA does read the minimum versison and enforces it with a stop loading and usually offers an upgrade <triplea minimumVersion="2.7.14848"/>

Help

.
All help buttons should say on the top line what the file being read/written is.
.
Repository
Most(51%+ probably much higher) maps repository name is the same as the xml name, The A&A style usually don’t.
If GitHub repository=xml name could say Published
.
GitHub Desktop vs Git-Scm

For us mere mortals GitHub Desktop is a better graphicial frontend to Git, yes? It is easier to use than Git-Scm (mainly command line)
Only downer is GitHub Desktop has no official Linux support.
.
FIles
Great addition, but;
I would increase font size and reduce the ‘white’ space between each line
Bolder green ticks, Orange o, Red already red !
This would make it more readable to my tired old eyes. 
.
Attachments
Make a column called Type, to list all the Attachment types
Remove the options word and put the numbers in Column headed Options
Two lines can be reduced to one saves boring scrolling, a lot.
‘White’ space
With heading like that you know what coming. 
Each of the pairs eg Name & relationshipTypeAttachment field can be on one line, saving hortizontal white space, so less scrolling, yay.

.
Map
Remove and add to the Map left hand pane all the View menus.
Note Connections & Neighbors are the same, so one can go anyway.
Assuming View into Map column above, then the Place contents can be on permanent display, probably over two lines, when the correct Map option (left hand pane is selected) less mouse work, or maybe for Expert mode?
.
Territories
The right hand should be a table, less scrolling, I know you can search, but with 800 TT/SZ its still a lot
Columns of TT/SZ name, Faction Owner, and PUs
Then you can sort by these columns as well as search.
