Maybe have a look at
PlasmaShop, Jonnee. It can not only open ELF Files, but also SDL, age, fni and so on files, basically everything except for prp, and it will display them in a nicely categorized view. It's really a pleasure to browse through the Uru files with that tool, and if you also install PrpShop, you can tell PlasmaShop where it lives and dive through prp files as well.
The libHSPlasma tools and Drizzle (and a good ol' editor) are really the only tools I use for Uru hacking today, and they both run on Linux natively
. Okay, PlasmaShop does not (yet) support Python files, but you can just add UruPython to your toolset and be done (Drizzle is usually only necessary if I want to edit a prp file, because PrpShop can only edit a small subset of the prp objects, and if I want to unpack and decompile Python files without using the Windows-only UruPython). For me, this works much better than PrpExplorer, ELFViewer, UruFun and what else I used to have installed.
