- new style string expressions - brace expressions to allow for tcl compilation - use "in" or not in (ni) operator instead of lsearch - bump version number
- fix bug with exporting multiple "unnamed files" to the file-system When there are multiple "unnamed files" in a directory, the constructed full_name might exist already. This would lead to an error in the "file copy" operation. Therefore, the code generates a new name with an alternate suffix in such cases.
