Well, I have a couple of small things to show this weekend.
The first is that I revised the Operational Commands menu for ports and naval bases. Here is how it looks now:

It's not that much different. I deleted the command for a "remove port" item in order to make room for the "Order Stores" item (Logistics, again!). Having the "remove port" function doesn't seem that useful, and I hadn't programmed it yet, anyway. There already is in the game the option to remove a naval base from a port. That is available in the Admin Interface (and I had done that already). The reason for a player to do this is mostly to save money. That's about the only real need to do that.
I also moved the "Improve Harbor" command to be next to the "Upgrade Port" command. This is somewhat more logical.
The difference between "supplies" and "stores" is that fleets don't - or won't - have anything like a supply train. After thinking about it, I decided that warships will be able to carry a 1/2-turn's worth of supplies. This is the old "cram everything you can on deck" sort of thing. I haven't programmed this yet, but I hope to be able to show it to you next weekend. You "load" those supplies using the "Gather Stores" command. The other logistics item, "Order Stores" will work about the same way as ordering a one-time supply delivery to a garrison. It will increase the number of strength points supplied by a port, until those extra stores are consumed.
I also finished off the actual implementation of the "Improve Harbor" and "Upgrade Port" items. The "Upgrade Port" will build a naval base (depot) if there isn't one already in place at that port. Otherwise, that command will upgrade the "Depot" attribute of the port, which is the value that corresponds to the naval base itself. This won't be used much, because sea warfare isn't very important in the period. So, a "default" naval base will usually be enough. But it may get used occasionally, particularly to upgrade a river base. Upgrading the "depot" mostly improves the training efficiency of a port. That "training" is done more or less automatically and adds experience points to naval units and allows them to eventually be promoted to a higher level of quality.
"Improve Harbor" will make one improvement to a port and/or its harbor based on the game's assessment of what is needed most. Here is an example:

In the Admin Dialog you can explicitly choose what you want to do, of course. Improve a harbor, upgrade the docks, add a lighthouse, etc. With the Ops Command, the game will decide what is most pressing. That's why the dialog shows what project you are starting in both the notes and in the details in the bottom left area of the dialog.
