1) Digging System - It's very hard to find out exactly what's flat, what needs to be dug, and what needs dirt. There has to be something that'll tell us exactly what's going on with our plot of land. This makes terraforming unbearable and complicated for any newcomer.
2) More Tooltips - Both food and inspirations don't tell you exactly what they're going to give you before you craft them. Sure the purity will change their results, but it'll still be nice to know the defaults, because not every food and inspiration is the same, they're used for entirely different things. We shouldn't be forced to keep checking the wiki so we can memorize every item in the game or gamble with our resources and hope that that's the item we were expecting.
To be honest, I've already quit this game and was planning on never returning until I was introduced the Enders Client. Now all my friends are using it so Salem can actually be payable. This 3rd party software adds features that should have already been in the game before it was released. These improvements are crucial and should be added as soon as possible, because it can deter players from the game rather quickly. Some things I can manage like running into trees because of the lack of path finding, but this is just too much. I also don't like the idea of relying on mods, because at some point they will get unstable and/or abandoned.
