Both of these seem to be Linux/X11 issues that I haven't seen (I have
to use Windows right now), and I don't really have time to look into
it in the near future.  One thing you can try is to disable
double-buffering in "src/ipe/canvas.cpp" (comment out the line
 
  iDoubleBuffer = db;

in Canvas::SetDoubleBuffer) and see whether this improves (2).

No wonder---they are not yet implemented.  Probably in preview 8.

Did you notice that Undo will bring your selection back?

I'll try to reproduce this.

Ipelets->Goodies->Precise stretch/rotate

This already works if you save and reload the file after adding the
style sheet.  Style sheet support in preview 8 is much improved
(including example style sheets in the manual).

In preview 8...

... which I plan to release tomorrow.
