The General page
The General page is what the bot looks after in your village between battles. Every line is a switch you can turn off. What it upgrades, and in which order, is on the Upgrades page. A change is saved the moment you make it, and the top of the page says when; there is no Save button.
Collecting
Collect resources
Collects the gold and elixir your collectors have gathered, and the dark elixir from the drills.
Collect the loot cart
Collects the loot cart at the edge of the map whenever there is something in it.
Collect Capital Gold
Collects the Capital Gold when its bubble shows over your village.
Tidying and rewards
Clear obstacles
Clears trees, rocks and other obstacles from the village.
Claim achievements
Claims the rewards for achievements you have completed.
Claim challenges
Claims the rewards for completed challenges.
Donating
Donate to clanmates
Every few minutes the bot opens the clan chat and fills your clanmates' requests: exactly what they asked for when they picked the troops, and dragons, balloons, giants and lightning spells when they left the choice to you. Donations are paid in elixir and dark elixir, never in gems.
For which account?
When you play several accounts in turn, each has its own General settings. The menu at the top right of the page says whose you are changing; see Accounts.
When two settings disagree
A setting that contradicts another is named at the top of the page in red, and nothing is saved until it is fixed.
