Have installed it for now and it doesn't look too bad. Has definitely moved forward from the K-9 days years ago. Will keep an eye on the development.
Most translators in open-source projects are pretty familiar with English. Usually they have a technological or background so English is a must. Often we struggle with translating terms into our very own language because at least in some cases they may sound a bit weird.
I personally tend to use English UIs in the software I use because it reduces the cognitive load off trying to figure out the exact term at hand, but for my 85yo mom that struggles with very basic stuff yeah I'm glad she has the choice to use Greek.
