Thank you for the great module which is very well designed and really handy.
Everything looks thought through except one tiny bit, the exposed aliases.
They turns out to be intrusive, i.e. they clash with my own pet aliases.
Aliases are handy indeed as such... but they are up to users.
Ironically es and sles are more likely to hurt exactly users who value and use aliases.
Some thoughts from @KirkMunro in his blog post To alias, or not to alias.
