Highlighter tool for scanned documents
Annotation of scanned documents is not easy - the highlighter does not work because it does not recognize the scanned text. Hence, I have to use drawing tool (which works but limits options for text highlighting).
It would be great if Xodo contained also free-drawing-highlighter.
Thanks for the feedback! Free highlighting is available on Xodo. You can learn more about this here: http://feedback.xodo.com/knowledgebase/articles/1861231-highlighting-anything-on-a-document

Most of my documents i read on this are book scans and i need to be able to free hand highlitght
Yes! That's what I need so much. It can't select or highlight texts in a converted pdf (ie. image to pdf). It will be a revolutionary feature if it added.

Need area highlight tool like foxit reader, it is very useful for highlight text in flattened PDFs.
First you should know what is area highlight tool in foxit.
In a flattened pdf we can't select text to highlight. In that case if we use ink tool, it looks like a extra layer. But the area highlight tool in foxit, intelligently highlights the blank area but not text area
The ink tool in xodo looks like a extra layer above the area (I hv tried in various opacity). But foxit area highlight tool looks like exactly same as we highlight text in a unflattened pdf.

text recognition may be the correct solution, but often the doc we annotate is not our own, but one provided, and perhaps shared among many ... we cannot ask all other readers to switch to the better OCR version, so having highlighter that works over the top of an image equally as well as over some text, as others suggest here, would be great
Using the rectangle tool is way less efficient and more time-consuming than having a freehand highlighter. You would have to adjust in two dimensions instead of just one. It also wouldn't show up as the same type of annotation in the Annotations window.
I work with scanned textbooks a lot, I understand this problem. You have to do OCR on your document first, then highlighting will work perfectly. You'll be able to even copy text after you do OCR. I use free tools like pdf xchange editor.

Would rectangle tool not help you with this?
For this to work select rectangle tool, select solid fill style (no stroke), and set opacity to some low value (e.g. 10-30%).
This could be user to highlight rectangular areas in scanned images.
