Could you do a video one day on theory and best practices for writing own minor modes? The biggest challenge I am facing is to properly restore the previous state when the minor is disabled some time after being enabled. Thanks!

Great presentations, thanks a lot for them. This one is particularly interesting if you are interested in writing you own packages.

One question: what is the package you are using to display the commands in the modeline as you type?

[anoopanthony]

how do i dim every closing parentheses ")"?

[AndersJackson]

Great presentation, like always.
1) What happen if there are two spaces after :tangel? Maybe search forward to beginning of next word?
2) What if something else is added to end of .ignore file? Maybe add and end tag, not just start tag?

[MarcoPrevedello]

Just my 2 cents: what about "dotctor.el"?
