Anacreon is almost entirely a mouse-driven game, with a few exceptions:

- messaging other players (rare)
- renaming planets (rare)
- reassigning production (common)
- deploying and transferring to/from fleets (common, can be done with clickable arrows, which are awkward to use)

The keyboard is used infrequently enough that it breaks the flow of gameplay in cases where its use is mandatory. For reassigning production and deploying and transferring fleets, it would be nice to have the option to select a value using a mouse-driven slider and/or the mouse's scrollwheel (preferred).
