Hey, you're right to think I'm pretty busy, heh. The progress has been a little slow the past few months.
The development is at a state where I can comfortably use the calendar for my purposes. I need to polish off some annoying bugs and make the UI usable on mobile phones, before I can make an official release.
I hope the long wait time ends up being worth it. It is a bit of a passion project and my perfectionism might show. Thanks for your early support of the project, btw, it was very heartwarming to see genuine interest.
P.S.: May I ask, what features do you personally find absolutely indispensable to add before you may consider using Luna as your primary calendar app? I.e., what is still missing that other alternatives do offer?
