The perfect sprite helper model

This was CamBen's idea:

About this issue, would it be possible to change which axis helper sprites use? I find the current one extremely difficult to select in the 3D view, especially since the center part of the model is practically nonexistent. Or maybe instead of changing the model, it could just have its collision updated so that it's overall easier to select?

The collision is actually just the visual geometry of the helper, not something separate. It's kinda tricky with sprites since sometimes you make them tiny and need it to be small so it doesn't obstruct your positioning view, but other times you have a massive bright sprite that you need to click from afar. And model is used for the sprite material, so we can't add the ability to swap between multiple helper models.

For changing geo, maybe adding a diamond in the middle, or adding spheres on the end of the axes to keep the middle clear?

I was thinking of a diamond/octahedron in the middle, but invisible/untextured so that it only serves for selection. Would that be possible?

Using WriteZ only seems to work fine, though it's visible in wireframe view. Doesn't matter too much.
