Something that I feel is missing and would really like to see in Camtasia is the addition of clean, callout lines. Similar to this screenshot. If Camtasia could figure out how to add this feature, I feel it would really elevate the software for training, education and teaching.
It would be better to raise this as an idea so that it can be voted on.
I like that style; it looks both clean and professional. Unfortunately that's not Camtasia's strength. You can simulate the effect to some extent by creating the lines from the basic annotation shapes and grouping them, but the second you resize the group the lines and shapes all change thickness, making them look inconsistent and amateurish. This is an issue that I've been griping about for some time with regard to text; I want to be able to fix the text at the size that I specify, not have the annotation play stretchy-squishie with it. It would need to be the same with these lines.
"Stretchy-Squishy" is a great way of putting that! Camtasia is such a great piece of software and it makes high-quality video production easy, but there are some components that feel so amateurish and out of place. Right there with you! I'm going to post this in the feature request area.
