"Connects -> Optimize routed tracks -> simple optimization" will
remove micro-lines.   Generally it is a good thing to do so - they are
a nuisance for hand editing, and prevent the mitering optimizer from
mitering corners that contain them.

One thing to be careful of is that removal of micro lines that are
inside a pad can cause a DRC violation.  They often appear for pads
that are off grid, connecting the nearest grid point to the pad
center.  Removal of these ones can cause a "insufficient copper join
overlap" DRC violation.  I suggest saving before trace optimizing, and
also running DRC and netlist optimization before and after, and
comparing results.
