I'm glad you like it! Adding measure numbers sounds like a great idea. I'll look at implementing it in the next update (1.0.5).
I'm also going to research how to best implement an offset feature. BagleBug previously gave similar feedback about wanting to set the offset, so you're not alone in wanting that in Konga Beat. I don't know if I'll have a solution ready for 1.0.5, but I'd like to add it in the following update.
I can't commit to a specific date because of work and other personal obligations. That said, I aim to release 1.0.5 in about ~2 weeks. In the meantime, if you run into any other pain points, please don't hesitate to let me know!
And don't worry if you haven't been able to do a perfect run of your songs yet. I would still be happy to include them in the showcase. 😊
