Bookbinder needs a queue + science suggestion
I think this has already been mentioned but thought I'd raise it again with my main concern which is without a queue the demand for science supplies in TO will quickly die off completely. Without a queue, even low level science buildings are enough for a player as their book binder will have a fairly large down time.
As another thought - perhaps trained specialists could require on-going training to keep them fresh. If they were not kept current their skills would stop working (not be lost though) until training resumed. Specialists could require something low such as a book every week or two and could use up a book relating to their highest skill so one trained using manuscripts would require a manuscript, ones trained with tomes would require a tome etc...
This would obviously require adjusted bookbinder building times and further thought but it would provide an on-going demand for science supplies. To build a whole bunch of highly trained specialists and keep them trained would require either a reasonable science industry or the purchase of relevant science supplies from TO. Would definitely encourage more investment in science supply chains and increase trade in science supplies.
