Autociv is a great mod for 0ad. It helps make hosting easier and faster, adds chat options like /link /mute and stuff, and provides a multitude of hotkeys so that you can pick and choose which ones are most useful for your gameplay. There are a bunch of hotkeys that are expected for a standard rts game, and none of them allow the player to move multiple actions into one button (this would be a macro and therefore cheating). While progui has some quite egregious macros, there was at least the positive vision of reducing the necessary clicks to play 0ad. The vision fell apart when reducing clicks turned into reducing actions, and then decisions; resulting in a more boring, automated gaming experience.
Among the most useful hotkeys for autociv are buttons you can assign to toggle through your buildings of that type. For example you can use a button to select each barracks one at a time and then proceed to tell it to get working even if your screen is not over the barracks. Even with these hotkeys, I still find that the fastest way to train with barracks and stables, or get upgrades with storehouses and blacksmiths is to manually click through them. This necessitates a click on the minimap to go to your base and then a double click to select all. I think these hotkeys that toggle through buildings should have a preference for the buildings that are idle, so that you don't have to search through each building to find the one or two that are idle.
I think this would enhance gameplay by improving the possible rate of multitasking. Keep in mind that these hotkeys do not reduce the actions and decisions a player must make, it just reduces the use of the mouse for those same actions. Because the player would then be able to train without looking back at the base, I'd consider it a big enough advantage (as well as an expected feature) that it should be available in the base game without getting autociv.
This being said, I know devs are busy with other things at the moment including performance, balance, and content. I'd mainly like to see what other people think about the idle preference for this hotkey including @nani who made autociv. Also, do you guys think it would be cool to have a visual queue that shows when a building is working or idle? For example blacksmith smoke could be only present (or maybe thicker/darker) when upgrades are being worked on, or maybe some action could be visible inside the stable or barracks to show training.
