Hi!
Right now, when you shift-click a banner, it goes into the fuel slot, which is quite frustrating. It would be nice if banner items automatically went into the banner slot.

Hmm should not happen in recent versions, what version and aircraft did you try?

v0.5.2 on 1.18.2 fabric, on a biplane. I checked updates using prism launcher a few days ago, so I'm unsure whether this is the newest version.

Ah yes, 1.18.2 has not been supported for a long time
