Right to Left Kerning

I’m using glyphs and love it!
the only problem for me is to kern right-to-left language.
when trying to kern it sets the reverse letters pair.

Did you select the RLT mode in the lower left corner of the edit window?
If so, please explain a bit more in detail what you do.

is this availiable in the Mini version?

No. Please see: http://www.glyphsapp.com/glyphs-mini
