Freezing the Main Info of a Mod When Scrolling

[campbell-godfrey]

Is your feature request related to a problem? Please describe.
If a user is scrolling through a number of maps within a mod, the main info at the top (Map Pack name, Type, Publisher Name, etc) is not visible on the screen, and it can be difficult for the user to synthesize information of a mod.

Describe the solution you'd like
The main info should be frozen like the header in place (underneath the header), fixing the top of a mod's white box in place.

Describe alternatives you've considered
Condensing information so that only 1 line of text needs to be frozen. The Olympus button & excessive info may make the screen too cluttered if too much information is frozen.

Additional context
Ignore the red images box.

The alternate solution has been implemented in #752. Actually freezing the top row of the mod will be much more complicated and can wait until later.
