Lasso select tool (feature request)

4

Freely-drawn selection boundaries are a pretty commonly-expected tool. This would involve [point-in-polygon (PIP)](https://en.wikipedia.org/wiki/Point_in_polygon) detection, which if I understand correctly is not implemented in SVG across all browsers. But, there are...

This only requires changing `startsWith` to `includes`. However, not everybody will want this behavior, so best to have it as an option. More generally, could take a binary comparison function...

Import the ~300k formulas from functions.wolfram.com

There are about 300,000 identities, expansions, special values, etc. at http://functions.wolfram.com/, in a structured computer-readable format ("Wolfram langauge"). It would be nice to populate the grimoire with as many of...

Feature request: when region is active, show word/line/char count in region

2

The strings %rw, %rl, and %rc could insert (i) an emptry string if no region is active, or (ii) the word/line/char count in the active region

For example, what Cook+Zalutskiy label as {2,2,8_0} and {2,2,8_1}

We should be able to subdivide intervals in a where we think the functions \omega(a) or A(a) are varying on smaller scales than currently sampled. See e.g. [this discussion](https://github.com/JuliaPlots/Plots.jl/issues/621) where...

The tolerance for computed continued fractions, `cf_tol`, should be related to the desired tolerance on omega, `tol`, by the gradient of the "objective function" (continued fraction equation). We can estimate...

Dynamic control of step size in a

Using curvature of omega(a) and A(a) can give estimates of delta_a which will potentially save computation time in smooth regions, and help to resolve fine features
