I know estimating software is problematic. I am worse than many at making estimates. Still, we must make plans.
Instead of giving a date two months hence for the browser, this time you said so for Qt 5. This is probably realistic, but past experience is that the job is quite large, and two months is not enough.
Then, after Qt is complete, then the Falkon browser will take some time to port. Is that two more months? Is July, 2020 a reasonable estimate now for Falkon?
Then, what about a reasonable debugging time for Falkon? Users will find problems that developers won't. So that will take some months to accomplish as well. Counting the debugging also as two months, it sounds like a reliable browser is about 6 months off, and funding is needed that VOICE cannot produce.
A reliable, modern browser will transform this platform. I have contributed in the past, and I intend to do so in the future. Thanks, Roderick, for organizing the funding of this project.
