Hi,
a new idea for managing bigger empires. Once you have more than one base planet for construction it would be nice if you could see the mineral statistic dependent upon those planets or bases to see if a local system runs out of specific minerals. So any way to be able to "split" the resource view on a specific selection of planet(s) or base(s) could come in handy that way.
Same with fuel, supplies etc.
Yes, this is planned for the 1.13.0 release

Tug Calculator: The one annoying thing with tugging space stations around is that you cannot see the max moving distance of the object to move. You can have a tug that can move on its own around 900bkm, but having a million t space station attached that max range can fall dramatically - and you eventually will run out of fuel with a not carefully planned tugging action.
So a tugging calculator would be nice. You can select your tug and that overview screen shows you the max tugging distance for all ships in your fleet which have no armor.
Doesn't A4xCalc already include a tugging calculator?
For SpaceMasters who manage more than one empire, it would be nice if the overview screen could display all messages sorted by empire. For select race you could add "SpaceMaster" and get an overview like this:
Greater Union
=========
Known aether rift growth rate reduction: 10%
Purchase minerals from Lalande Resource Group but no mass driver destination is set
System Artemis is not fully geo surveyed. Bodes: 112. Surveyed bodes: 59
Space Alliance
=========
Wreck of ship class Galaxy Mk.2 located in System Barnards Star
Ship Iceland 001 of fleet Encke Space Station has only 0% of MSPs left
System Beowulf is not fully geo surveyed. Bodes: 409. Surveyed bodes: 88
I'll see what I can do here.
Also: you can select those messages but not copy the text to an external text editor. Would be a nice QoL 
This will be possible with the next version of AuroraMarvin. Thanks a lot for all your suggestions!
