Ideally - if designing it from a completely clean sheet, you want it

f
might be good.
This is so autocorrection software can function well.
Then there is the fun question of how many 'initial' points, and how
many vectors per point.
10 numbers, with 8 drags from each number gives you alphanumeric, and
easily 30 common phrases, or word components.
'I'll be ' 'home ' 'at ' '6' 'P' 'M' ' ' 'Love you!'
In 8 strokes.
If you go slightly further, and each stroke can either terminate
normally, go longer, go clockwise, go anticlockwise, or return, that
takes you up to 5 per stroke, or 400 'keys'.
It would be lovely if this was incrementally learnable.
First level - press 0, hold, get
d
a 0 q
f
splashing out.
Once you're comfortable, you get
D d Q
a 0 q
A f F
Drag and hold to F, and you get
Finish First
Found F
Find Friday
( down-right stroke from 0 = F, turning clockwise is Find )
And the words for 'f' might be 'food, friend, ...'
Being silly, you can then hold on food, and go out to 'pizza, chips,
kebab, lunch'

One thing to do is look at existing designs for reference/inspiration.
I mentioned the fitaly layout in a different post, but here is a link to
help with the visualization.

Auto-correction software is great when it works, but annoying when it
doesn't. So it should be configurable and not mandatory. You had some
good ideas in there. The food => 'pizza, chips, kebab, lunch' is
stretching it a little bit, but still not a bad idea.
