Wiz: might be that a reserve army is a feature suggestions, but it has been needed for some time and fits the period where this had been used as a way to prepare for war. Since we have force limit and the manpower burns faster than ever these days, there are plenty of limitations to implementing this system. Just make half the cost of it, while burning manpower to keep it at full strength, by burning manpower is just another way of saying that increasing the reserve and army to more than your manpower increase should not be a viable option. Like having 1 main and 3 reserve AND a full manpower reserve makes it illogical and quiete impossible (since if the armies are larger than able men to be in them, manpower should decrease since they draw from the reserve of the reserve).
However the way this could be implemented, it´s been needed for a long time, since for prolonged peace, you really only need the MP, the army crushing rebels.
Viper/Arumba: (believe it´s the same, or I got something wrong) About fleet transportation, there is another major drawback from using automated transport. While I still use it when I have stuff to do elsewhere in a war, it´s VERY bad to use as a means of invasion, even if just crossing a strait. Apart from the shorter travel time, when you manually set your troops to the ships at port, they will be divided into an even fraction of your army WITH the general. On automated most often it´s some bad mix of troops getting there first and the general is left behind.
While there is no problem at peace or moving into secured location, if you have a landing party they will be smashed to pieces since they most of the time are badly mixed and without a general. While I like the idea of reinforcing the army and hoping for the next batch of guys to land before morale runs dry, I hate it when troops are transported in a way that opposes what the system already does and recoignize but also just make me do stupid mistakes.
otherwise, great list

Wouldn´t have minded a mapmode for finding allies, perhaps with possible allies too if improved relations instead of truce-map since I got the alert on the top and use that to see when I can attack. Afterall, the important targets I always knows which names they have. But searching for a new ally when an alliance is broken is tedious and if you can´t wait for the AI to send a request because blobbing-McFrankenstein sits next to you glaring at your provinces, I just really need to asses which allies I can get now by an easy way.
