I completely agree.
You only have to browse the code of both to see how well coded hamsterfiler is.
I don't think hamsterfiler needs any updates but I am sure if required gidzzz would get round to it. I imagine a large amount of the developers "Maemo time" goes into OMP as that was inherited code compared to hamster.

It's a very well thought out application hamster and has no awkward dependencies from other repos like alternatives.
