Show exact amount in tooltip (or either by click?)

[mclate]

Right now Fava rounds all amounts to two digits (i.e., 1.23 USD). Generally it is ok, however, for some other currencies/tokens (say, BTC), it is common to have very small fractions (i.e., 0.003242 BTC). Fava will show such small amounts as 0.00 BTC.

The idea here is to show the exact amount in the tooltip (right now all tooltips show None which is very much a pythonic value and i'm not sure where it's coming from) or toggle rounding when amount is clicked: once clicked, it will show exact amount and revert to rounded one if clicked again.

I just found where this happens in the code, so if this idea makes to the community, i'll be happy to implement the changes in PR

That's not quite correct - Beancount and Fava infer the most commonly used precision (see the dcontext on the options page) and use that.

In any case, I like your suggestion of showing the precise amount in the tooltip, a PR for that would be welcome :) I'll fix the None occuring in the title.
