As well as fixing an issue with scrolling introduced in v20, this release adds the multigraph command:

It's now possible to display multiple lines on the same graph using mg instead of g:
mg <func_name> <var>=val1[,val2,...] [axis [, axis]]

For instance, to explore the changing cutoff frequencies of a Sallen-Key filter with two 22nF capacitors, a range of fixed values for R1 and a 20kohm potentiometer for R2:

lite-mode

theme lite and theme dark let you switch modes, so molencalc works better in a bright room, while still being easy on the eyes when it gets dark

As of v20, it's now possible to use the arrow keys to move through the current text you're editing, as well as moving back and forth through things you've already entered. Pretty basic stuff on the face of it, but it was surprisingly fiddly to get right...

Version 18 adds some new commands that let you explore some nice chaotic systems based on examples from Elegant Chaos

dd [damping] [omega] - an animated phase space plot of a forced damped pendulum system
pd [damping] [omega] - an animated Poincaré slice through the same plot as above (shown in picture)
df [damping] [omega] - as dd, but for a forced van der Pol oscillator
pf [damping] [omega] - the Poincaré slice through the above
ds [x_initial] [v_initial] - as dd but for a system with a signum operation in the middle of it
ps [x_initial] [v_initial] - the Poincaré slice through the above
