Use conditional formatting sparingly
A client has recently asked me: "I read in on of your articles that calculated fields are faster than conditional formatting. Why is that?" FileMaker has to evaluate all conditions every time it renders the conditionally formatted object., while the Case function exits as soon as it reaches the first condition that's true.
Convert FileMaker Styled Text to HTML
If you care about text styles then you care about presentation. And if the text you produce is going to be presented in the digital world, such as on a website or in an e-mail client, or any other platform based on HTML and CSS, then you should pay attention to what the HTML you produce tells about you, both to humans and to computers.
