Added:
*Since the introduction of the new spy random, it became obvious that there will always be states that you can not break with spies. But you can see enemies networth, you know how much land he's got, how many spies he MUST have, so you can calculate how much infantry is required to break in SA. Note that this only applies if enemy has only spies and infantry, so you actually need to send less infantry. This tool is found in 'Random' page.
*Cleaned the workpage a bit, hid the unnecessary pages.
No macro free version, this means that you will be asked, each time you start the workpage, if you want to allow macros. I used macros for 2 buttons so they delete everything from the 'Your army' boxes. So it's not necessary at all to allow macros.
Since my set is over this month, I'll do some random stuff and probably come up with new things to add for the next version. I was thinking to find out the exact land grab formula and finding out how much army you'll lose in an attack.
Is anybody even using this? Is it difficult to use/get used to?
