How about some more standard scale presets?
Yes, I realise we can map our own, but thats a bit cumbersome to do on a per-patch basis and the default selection in there seems a bit, well, random to say the least!
It’s missing common western modes, i.e. Dorian, Phrygian, etc.
To have Balinese pentatonic, but not a regular pentatonic minor? That’s kinda weird…
Hey, thank you for the suggestion, we can extend the list of presets, a list of the scales and modes you and others would like to see included would be very helpful. 
Well I’d definitely start with the standard western modes, i.e.
I Ionian W–W–H–W–W–W–H (Major)
II Dorian W–H–W–W–W–H–W
III Phrygian H–W–W–W–H–W–W
IV Lydian W–W–W–H–W–W–H
V Mixolydian W–W–H–W–W–H–W
VI Aeolian W–H–W–W–H–W–W (Minor)
VII Locrian H–W–W–H–W–W–W (though only complete lunatics ever use Locrian!)
Obviously the major/minor are already covered, but it would make sense to have all those for starters
Personally I use Phrygian, Harmonic Minor and the Spanish Gypsy (which is the 5th mode of harmonic minor) a lot. (Revealing my mis-spent youth of Goa Trance and Ozric Tentacles now…)
Harmonic Minor
1, 2, ♭3, 4, 5, ♭6, 7, 1
Spanish Gypsy (Phrygian Dominant)
1, ♭2, 3, 4, 5, ♭6, ♭7, 1
Hopefully others will find this useful and chip in some suggestions too…
If you want to include absolutely everything, this is a nice overview of 167 different scales (of which the first 86 are probably the most useful). It’s implemented in the MidiAlf and is a great way to try out different styles. Personally, I’d be satisfied with the pentatonic scales and the ones @RiK mentioned, because I’m so very conventional
