I have also been wanting basically everything on this list (and more). Some of the suggestions are on user voice, so give a few votes if you see ones you really like.https://warlight.uservoice.com/forums/77051-warzone-features?query=Idle
The difference between the time (session age) it takes me to finish manually, and the time it takes my autos to finish is huge. I've also had quite a few mishaps with opening the wrong level with autos still enabled. I've found that, in general, the autos tend to do more harm than good on the regular levels if left enabled, except at the very beginning. The exceptions to this are auto-draft and auto-smelt, which I nearly always use.
There are other features I would like, such as:
1. Suspend or reduce auto-conquer while a hospital is upgrading (continue capturing free to take territories during this time).
2. Upgrade hospitals when the value of the upgrades is expected to cost less per army than the most expensive mercenary. This can be an estimate. For example, upgrade a hospital when the following equation is less than the most expensive mercenary would be:
upgrade cost / (new distant savings - old distant savings) / number of territories left
3. Allow me to set different defaults for battles, regular levels, and challenges.
4. Provide an interface that lets me create rules for when to use autos.
