Two suggestions spawned by a thread in the ATCA:
1) Put an "average time spares will last" number on the Class summary. The huge annual breakdown rate numbers on big ships are confusing to a lot of people (it seems), and the important number is how many years it will take for your spares to run out. As it is, I just realized that I always do the worst-case calculation in my head - it would simplify my life to have Aurora do it for me, especially if it also told me the average (in addition to max) breakdown cost.
2) "Conventional" fighter engines. Now that we've go company-sized drop bays, I just design my first assault shuttle - it comes in at 350 tons. Unfortunately, I can't make it a fighter because I haven't researched fighter-engine tech yet. It would be nice to be able to research a fighter-type engine (that will flag a design as a fighter) without going to the fighter power-level, e.g. use GB power-level instead.
As another possibility, you could have a checkbox on the F5 design tab that specified a ship as a fighter (independent of engines), with a design error if it was over 500 tons.
As a gripping possibility, you could just specify any ship of 500 tons or less as a "small craft", which is built through construction factories rather than through SY. This is actually probably the simplest (and best?) option.
The main impetus for this is that it doesn't seem consistent for whether or not something is classified as a small craft (built in factories) depends on the type of engines it has, with the more sophisticated (fighter) engines requiring factory (less specialized) rather than SY (more specialized) to consturct.
Another thought - put in a passenger compartment for e.g. 30-50 passengers that's the same size as a company-size drop bay. This would allow us to build an "admiral's barge". OTOH, it's getting dangerously close to removing the abstraction that cargo lighters are hidden in the mass cost of CHS and spaceports.
And another thought...I still think that CHS size should probably be bumped up, at least by 2x and possibly as much as 5x. As it stands, it's negligible relative to the size of the cargo holds.

PS - See, still got that counting issue
