One thing that frustrates me about Photoshop is that unlike other programs with a Layers feature, you can't put more than one "text block" in a single layer. If you want text to appear in your image in different locations, you have to create a text layer for each instance (or drag out a bounding box for a Text Area and then get creative with your space bar — ugh).

Speaking of fonts, have you ever needed to match an existing font you didn't recognize? And it's no longer a "font" into which you click an insertion bar and see what the font menu says? Perhaps the type in the artwork you're given to work with has been converted to outlines or rasterized, or worse, all you've got is a printed sample.
