Usually dev's gives higher and not worse discounts, if a game gets older

Can you put all the patients in a "quest" on priority at once, instead of selecting and clicking on them 1 by 1 ad nauseam? Is there a way to put researchers so they just automatically research anything with the lowest rating? I find myself having to click on them 1 by 1, looking at what rating they are, then trying to remember that as I click on the rest. Also what happens if you don't set a research priority? Do doctors automatically go work in a room they are specialized in after they get off break...

I find that the sandbox is way too easy compared to 2PH - to the point that I just lose interest because there's zero challenge. But challenge mode is much much harder and is rendered borderline impossible by the fact that you can't send a patient home so I feel like I have zero control. Is it just me that would much rather have something in between in terms of the level of difficulty?...

The game definietely looks interesting - but how is the difficulty of the game? I'm looking for some challenge tho - are there any challenges where you are running out of funds or have other disasters - or it's rather a chill casual type of game?

Can't get past 4.2 stars anyone else having this issue? I've had no issues getting 5 stars up until this point.
