Feature request: File-selection capabilities

Right now the only way to select a file to use in LOAD81 is at the command line. On the Open Pandora, we have the PickleLauncher tool:

This is a generalized launcher for cmd-line programs which only accept filenames on the arguments, and for now it works very well as an 'outer shell' for LOAD81 - picklelauncher -> [user selects file] -> LOAD81 -> [user ESCAPES LOAD81] -> picklelauncher -> etc. The 'piped-tools' approach could be used for this feature, or LOAD81 could have its own file-selector capability built in as the Editor functionality expands.
