Until the last release of GWorkspace, I've used exactly this solution.
But, even if the method used to synchronize the icon path with the browser
columns was 90% copied from a openstep app found in IconKit-4.2, I've
always had many problems.

I've also had a (little) modified version that ran well on openstep but
gave many problems with gnustep...

Actually, there is not a 'icon path' anymore.
Instead, each icon belows to its column and the scroller is the NSBrowser
scroller moved on the top.
In [GWBrowser _tile] all the stuff is automatically drawn in the right
place...

It is not my intention to split the development/debugging of NSBrowser,
also because, actually, the GWBrowser class is good *as it is*; only some
debugging is needed.

I've only thinked that this is a reasonable and more efficient solution...
