Dual-pane file manager for Mac, Windows and Linux

Hate to say it but a 'plugin system' for a gui application is a bad smell. Look at plugins for hyper -- people write a few and then quit. That's the good outcome.

A more likely outcome is to be like Eclipse which more or less works out of the box to develop Java, occasionally gets a group of plugins put together by a vendor that works, but it will fail if you install enough of them.

The trouble is that current gui frameworks do not support encapsulation in that there is a single thread used to draw everything. If component A takes 10 sec to draw, component B has to wait.

This feels good to use. Is there "quicklook"? When I press spacebar it selects the file.

Update: Michael got back to me via email and pointed out there's a quicklook plugin.
