Inkscape

This emulates Inkscape v1.3 gui add_symbol action but also:
-Adds each selected object individually NOT grouped as a single symbol.
-Alpha-Numeric and Canvas Position sorting options.
-Auto-labelling options.
-Sorting adjusts object z-axis like Rob Antonishen's restack extn.
*NEW* - Alpha-Numeric Sort can be interleaved with existing symbols.
-Positional Sort does NOT interact with pre-existing symbols. New symbols added below existing.
-Adds an editable Title element to symbol if object title blank. Allows easier retroactive symbol label/name adjustment.
-Also includes Quick Add extn which batch adds selected objects unsorted. But .inx adjustable to create own preset of main extn; see readme.txt.
-Help and Troubleshooting advice in extension dialogue

-For use in managing symbol library file and is intended to aid symbol library creation only. Other uses not tested.

-"Symbols Batch Sort and Add..." + "Quick Batch Add Symbols" Placed in Extensions>Symbols
-As with any v1
