Styling should be fairly consistent to the rest of the project. As a general rule of thumb:
if (false) {
return true;
}
Spaces before/after ()'s and every if statement should have {}'s. On top of that curly braces should be same line. Worst case I can fix formatting pretty easily so it's not that big of a deal.
Please comment your code so it is easier to tell what it does. That helps every contributor a ton in the long run.
Most features should have a decent amount of customization so that clients can toggle features.
