Thunar queued job execution

[Stefan Mitić]

Hi flo, OmegaPhil,

flo, thanks for the heads-up, I was aware of that and that's why I plan to
avoid changing anything related to how Xfce handles tasks/jobs. My idea is
to add something like a scheduler that will take care of when a Thunar job
is run/created. After the creation of the job everything is left to the
underlying systems. This should avoid problems with any other system also
relying on Exo or any other underlying system.

OmegaPhil, I will certainly do that before I start working on the
implementation. Thanks for this link/resource, I tried to find some file
manager with that capability but wasn't able to.

Regards,
Stefan Mitic
