Paroli is indeed themeable. Due to its plugin-nature every app comes 
with its own edc files that can be adapted which is highly encouraged.
If anyone wants to give it a go or improve the default design get in 
touch with me, I help where I can.

I like the idea of adding small hints and had thought about a "first 
use" mode myself. my idea included windows explaining the screens, but 
you approach is much nicer :)

> * No colours (delete, recharge, adding name)

Recharging should turn the battery icon yellow and delete should be red 
everywhere ... I am open to more color as well, although I do like the 
combination of black and white as the dominating "colors" and would like 
the standard theme to keep this focus, but then again I am no designer.

That is more my fault than a design issue, that can be fixed.

That I already implemented (after reading this mail), it is currently 
still only on my machine as the commit would break other things, but it 
is done :)

Maybe a little magnifying glass in "beginner" mode when no number is 
entered and a "+" once a number has been entered?

hehe, yeah, that is listed just not a high priority for now

I am fighting this since I first changed profiles...I hunting and hope 
to get this fixed.

hmm, I think graphical scale wouldn't be too readable either ... I am 
personally not a big fan of the % sign. Any icon ideas anyone?

I think I don't get the message...

That also depends on you liking I guess... I don't find them too bad. 
Opinions anyone?

Hehe, I got so used to the names I don't even notice them anymore.

Making them bigger I agree, we should do that. The text based output ... 
difficult as the text would need to change according to number etc. I 
prefer the numbers (from an implementation point of view as well as

I haven't spend any time in position those buttons, it is elm's standard 
behavior, so there was no intention behind it.

Apps never have a back-button, they are closed using the topbar. 
Subwindows should always have a back-button which allows you to navigate 
an app without closing it.

Good one, in fact I would like next and back to be icons only which 
would limit the potential translation effort again.

Your app can be designed as you see fit. Using what is already available 
in paroli as in design files as well as gui classes might just make your 
work easier.

There are no documents, so you are free to do as you please. If you have 
questions or want to know how stuff currently works I am glad to help 
and we could start documenting from there.
