Thanks for your tips, especially the shortcut keys. I really should start using agent armies myself.

A few small things I disagree on, the main one being clean up armies. I find this option, if enabled so annoying

If you go for a generalised army as I do (4 spear, 4 ranged, 2 sword, 2 axe or other armour piercing, 2 or 4 horse depending on unit sizes) and often have two full armies in a rpovince together at the end of a year it mixes them up

Also auto-merge isn;t actually very usefull. I quite often have two partial units that I want to keep, for example two catapaults with 4 people in each, which can both be retrained in seperate provinces in only one year, same for any more-than-one year units. This is especially true of beserkers in VI. Also I go for seperate stacks of partials to go and retrain in a province with the best armour/weapons/moral bonusses, and if set to clean up armies they will mix with other armies along the way every time.
