lean rss reader

edit: make some parts bold
it's not (yet) an app request.
trying to find a lean rss reader as my old is trash.
don't know if we can finalize rssowl which i only heard good things about.
i stumbled upon makagiga.
it's not clear to me if it's portable.
not sure if it was portable or had also a portable version (by developer).
i found different info on the net.
the developers site tells the the installed version can be run portable.
as i don't want to install but use portable apps from the begining that is nothing for me.
however, i'm asking for feedback.
did anyone used the actual version for windows?
i'm pretty confused about portable apps as i found at least 3 types of them as my other thread says.
hope for clearence.
thanx!
