I tried to find nabla (∇) as it is a very common symbol in engineering. Tried 'differential', 'derivative', 'delta', even 'triangle', but didn't get it.

Finally tried 'nabla'. Turns out it's just not there :(

Just added it. Thanks.

I'll try to import a larger set of symbols soon, to fix the gaps.

Proportional to is missing too. ‘propto’ ∝

Arrows would be good to have too.
