There's no documentation on a lot of this mod, but in particular, how does one "charge/discharge items in terminal directly"? This seems like a big part of the mod, but there's only a single blurb on most features, and no examples or instructions on how to actually... do these things?

it has a ingame guide now

The in-game guide has not been updated to add the information on charging/discharging items directly from the AE2 terminal, as was specifically requested. The issue has not been addressed.
