open multiple files by spawning mulitple programs

[evanescente-ondine]

Hi,
the default behavior, is to either open all files in the program if it's tolerated (micro for instance) then if other files needs other handlers, open them after the first has closed... I don't like that, and I don't like using the tab feature of micro either.
Could it be possible to specify something like that:

handlr set 'text/*' "footclient micro {each}"
and be default if several handlers are needed, open them all simultaneously... perhaps in different tmux session ?
