Feature Request: Set Icon Indicator Position

[marcxjo]

The dock sets icon indicators on the panel's outermost edge, i.e. the panel edge which coincides with the screen edge. At least for me, this is a bit unexpected, and I'd personally like to be able to set the indicator on the panel's inner edge. (For example, on my screen, the dock lives in a top panel; I'd like to see indicators on the panel's bottom edge.)

Thinking this needn't be too complicated; could be another dropdown in the Appearances section of the Preferences window; probably only needs two settings to start, one for the panel's inner or outer edge. (Indicators perpendicular to these edges seem weird to me, but as with anything, I could always be over-assuming.)

I'll let more qualified folks decide what the terminology should be for the position choices, but I will emphasize that it should probably account for the case of vertical panels (i.e., left or right screen edge), hence why I use the terms "inner edge" and "outer edge" above.

In terms of settings storage, something like prefs/indicator-position with an enum value probably makes the most sense. (Don't mean to backseat dev with any of the above details; just trying to help make someone's life easier if this gets picked up.)

I don't have much experience with Python, but I'm more than happy to help in any way I can if there's interest in adding this.
