So this is a double complaint, that it's (1) a small update, and (2) a membership only update?
Don't see the point of complaining about this. I will admit that the 5.19 update was lacklustre compared to other updates, but I'll also admit that it's not the first update I've been disappointed with, there's been a number which didn't have much to offer me in particular. But there have been others which had tons, and some which had just a bit but was actually pretty exciting.
Were you also disappointed with 5.17 b/c the focus was on mod making and you you don't make mods? And 5.16.1 b/c it was just a Unity upgrade?
I also don't get the purpose of the comment of this statement:
add this few of a breakthrough and then call it a day
This implies that he's not working on any other improvements to the game, which is silly. There's probably some reason he decided it was time for an update, and this was the only thing that was ready to go. Would you really rather him not release the Standalone App Tabs update and just save it for when there are other updates just for the sake of having a 'big' update? In the end, what does it really matter? Why are you so passionate about this one particular update?
