If the feature request is for a plugin or theme, specify it here.

common-aliases plugin

If the feature solves a problem you have, specify it here.

The current file extension aliases are currently as follows:

Alias	Command	Description
pdf	acroread	Opens up a document using acroread
ps	gv	Opens up a .ps file using gv
dvi	xdvi	Opens up a .dvi file using xdvi
chm	xchm	Opens up a .chm file using xchm
djvu	djview	Opens up a .djvu file using djview

This seems closely tied to a particular (and aging) set of software.

Describe the proposed feature.

I think the lowest-effort solution these days would be to use xdg-open for these file types.

Describe alternatives you've considered

A more robust solution would be to have some dynamic validation of what softwares are available and to choose something appropriate to the environment. OSX, for instance, provides the open command.
