Those are, ab initio, reasonable suggestions for syntax. Buy the 
parentheses notation is already, as I understand it, in train for tabf; 
we should be consistent. And parentheses are the most flexible; the 
modifiers can be separated by commas and/or nested.

Is it also planned to enable frac(Axxxxxx) to point to the denominator 
or numerator sequence? And then click on it to show the fractions?

Yes, it would be nice to be able to search for these things by
keyword. I've toyed with the idea of mimicking the CSS |= selector by
writing

fini-conj (or even fini-?)

which allows additional levels to be added if needed.

This doesn't obviate the need for comments, but allows for much easier
searching.
