Hi Joris,

Thanks for responding.

First, the explicit sizes are no longer documented in the manual.
Instead, in sec. 3.4 the manual says that if you want delimiters of of a
particular size, use Format -> Transform -> Resize object to resize the
expression. Resizing the expression does not make any sense to me.

Second, there seems to be some (unwanted) interaction with other
features. For example, if you disable matching delimiters, type an
expression with \left|(|1 ... \right|)|1, i.e. parentheses of size 1, if
you copy and paste this expression somewhere else, the parenthesis size
may change. I say "may", not "will", because I haven't exactly isolated
the conditions under which this happens.

Anyhow, I consider delimiters of specified sizes a very important
feature, and I'd like to see it preserved.
How would MathML-style delimiters work?
