I haven't used the qt toolkit a lot as a number of things do not work yet;
panning is one of them.
But qt seems to work a lot faster and smoother than fltk.

It absolutely is.

A serious issue for me is the OpenGL single precision. I often work with
time series from the late 19th century to date (datenum order ~ 733000) and
those time series get severely distorted due to insufficient precision.  See
bugs #40246, #33748 and #32980.

Default: as long as classdef is still experimental, not much.
Support for I/O of classdef objects in .mat files would be wonderful when
classdef gets more mature. But of course that's the wish list, not a
showstopper bug.

A while ago you mentioned you'd liked to have xlsread & xlswrite in core
Octave. I'm almost ready to amend the io package to make that happen, but I
could use some guidance; I've made some remarks and asked some questions in
the thread in question
(http://octave.1599824.n4.nabble.com/Spreadsheet-support-in-core-Octave-instead-of-io-package-tt4666947.html#a4666962).
One is what parts can go to core Octave first, what parts can follow later
and what parts should rather stay in the io package. 
Plus of course, from the POV of a package maintainer, how to manage io
package support for the then newest and older versions of Octave.
