Krone aims to be a very simple program for managing only expenses and printing weekly/montly/annual reports. The purpose of Krone is to replace a Mac programme called Burn, which the customer used before.
I have used Qt for personal projects for several years and I have written some small patches for KDE programs, but this is the first time I have written a KDE application from scratch, and this has confirmed what I already thought: the KDE libraries are absolutely fantastic!
I don't really have too much time to code, as I am a student and have another job, but I usually spend an hour or so during the day to code or read documentation. Hopefully Krone will be usable within a month or so, but it is a bit hard to predict.
The attached screenshot shows Krone as of today: it is still many hours of work from being usable, but you get an idea.
