It's not like 0.3 isn't playable or enjoyable in the meantime. We'd all love 0.4 to be ready right now, but the team needs to do what needs to be done still. I believe that @Sam and the team have shown nothing but the utmost commitment to this so let's just enjoy 0.3 in the meantime. Some things in life are just worth waiting for. Like a fine wine.
I'd rather wait so that whatever necessary fixes and tweaks are done before it's launched. This way, LSPDFR 0.4 will be:
Great? Absolutely.
Amazing? Definitely.
Hotel? Trivago.
