+* 'gsort' or 'tables' or 'filter' command. Distinction is that this
+ comamnd is object-aware and can process geometry by name in a given
+ column or list. This way, one could sort output from search, nirt,
+ idents, and other table/list-based commands. Examples:
+
+ Sort by data size: [gsort -size [search .]])
+ Reverse sort of col4 by vol: [gsort -volume -k4 -r [search .]])
+
+ Desirable to intentionally pattern after POSIX sort
+ (https://pubs.opengroup.org/onlinepubs/9699919799/utilities/sort.html),
+ adding geometry extensions similar to BSD sort(1).

* 'layer' command: to create, select, delete, list enable/disable
on/off, lock/unlock, and set other properties (e.g., color, style).
need subcommand(s) to move geometry to/from layers, perhaps

-* 'tables' command: do not call system() on the "sort" unix command!
- It should perform all sorting on the data directly in memory, at
- least without creating another process. bad security practice.
-
* 'text' command: imports a text file (as geometry). have options to
specify the spacing between lines, first line, #lines,
underline/overline each line, convert to all upper/lower, position.
