When I launch a task config, its name shows up in the monitor tab. If I later modify the task config (eg update the wdl snapshot or edit the fields), all previously launched task configs now show up with a string of random letters appended.
While it may make sense to be able to distinguish between versions of the task configs that have been launched, it would be better to use a more human readable name. One suggestion would be "_Vx.y", applied to all config launches rather than only after a change. x = the wdl snapshot, y = the sequential version number of the edit to task config fields.
