This Steam thread could help you. It talks about 4K resolution, but it explains why the game can become blurry, especially on Windows 10 as it has the Display scaling turned on.
Just disable the Windows scaling or the DPI of the game and that should fix the issue.
Try going to your User folder on your computer, there you can find the Zomboid folder.
In that folder, open and edit the "options" file. You can change the resolution at the top of the file and save it.
Okay, now being able to build zombie cages in order to counter or distract hostile npcs or players would be pretty sweet ngl.
Though this does bring back old memories of Pre Build 41 days where survivor homes (the ones that are boarded up) inexplicably have about 20-30 zombies locked in them.
Kinda his fault yeah, you know it's a special attack which is going to take more time than a normal attack so obviously don't do it if there are 2 zombies too close to each other.
Other than that I totally agree with the clunky movments
