All of this has been discussed in detail on the Discord server.
One thing I would personally change is the order of the drawing information, to one that's "from general info towards detailed info": Category (real...) > Country > Type (cruiser...) > Class > Ship.
Yes, the order and display of the table showing the drawings is extremely temporary. The finalized version will show thumbnails for various pre-configured views that will replicate what we have on the main archive.
I think that the current list of categories is just temporary one, merely to show "something" in place, that's why I made no remarks about it.
This is correct.
Btw. Maybe it would be practical (or maybe not - just a loose idea) to make these categories for selection in the upper window more general (wide) - so instead of Aircraft Carriers (and by implication, separately Helicopter Carriers, Seaplane Carriers etc.) just Aviation Ships, not make separate minelayers and minesweepers but just mine warfare vessels etc., and detailed category would be just mentioned on the list of ships (search results)?
We are implementing a "Sub Type" feature for each Class to enable more detailed specification.
For instance, the broad type "Aircraft Carrier" might have several different Sub-Types associate with it (Helicopter Carrier, Attack Carrier, etc).
