-# + fix bug with consecutive path coordinates not being translated properly to relative commands
-# + convert straight curves to lines
-# + eliminate last segment in a polygon
-# - provide command-line option to disable raster-to-base64 conversion
+# + add option to keep inkscape, adobe, sodipodi elements and attributes
+# - ensure a really good understanding of prec vs. quantize and what I want --set-precision to do
+# - enable the precision argument to affect all numbers: polygon points, lengths, coordinates
 # - remove id if it matches the Inkscape-style of IDs (also provide a switch to disable this)
 # - convert polygons/polylines to path? (actually the change in semantics may not be worth the marginal savings)
 # - prevent elements from being stripped if they are referenced in a <style> element
