Is it bug that naval admin commanders (general or industrial) don't give any bonuses from their Production skill to stabilising lagrange point ship? Only production skill of ship commander gives bonus. Ship is in naval admin radius at this moment of course.

I think it'd be nice to be able to raise the wealth cap, either via tech or via settings. It'd be fun to roleplay as a vast empire with an enormous debt but huge reserves, having a decade-spanning long economic panic - and I think it might've been mentioned as something that was planned to change back in the C# patch notes (I'd link but I'm stuck on mobile at the moment).

This is not really true. Analysis done by many folks here has shown that heavy armor is generally a less efficient use of BP than light armor/infantry and will end up suffering higher loss rates (in BP) than the lighter units. This doesn't make heavy armor useless at all, as it remains useful in tonnage-bottlenecked situations, but to say that the current model favors heavy armor is not correct.

Yes, your right. That conclusion was filtered through an assumed tonnage limit as almost always the main practical limit for my invasions in in how much invasion tonnage I can bring.

And I did not mean the specific unit type heavy armor, but all units with heavier armour than infantry (so including also stuff like powered INF armour).

Ground Commander tactical effects the Hit Chance of STO weapons under command AFAIK. It has no effect on ground combat

While playing Aurora, making notes to not forget about what could be improved.
Few simple suggestions for UI:

1) Economics >> Industry
- add "Construction Rate" per factory indicator, along with "Construction Capacity"; currently only way to check it is to open Race Information, which is in different window

2) Economics >> Shipyards
- it seems, upgrading SY requires some minerals along with wealth, so it would be super handy to have this information in additional columns, for example

3) Economics >> Research
- add "Research Rate" per lab; currently only way to check it is to open Race Information

4) Economics >> GU Training
- add information about minerals cost for training Ground Forces, currently it is only "BP cost" column
- add "Ground Formation Construction Rate" indicator, currently it is in Race Information

5) Ground Forces >> Formation Templates
- for Show/Hide Obsolete models - make obsolete ones visually distinctive from current ones, by changing font colour (white=>gray, for example)

6) Events
- same as for show/hide obsolete models, make filtered events visually distinctive in some way (rarely needed, but I recently misclicked button in Events window and hide certain type of event for many years until I figured something is wrong, well:))
