Love your work and thanks for building this amazing tool. We are evaluating some tools to use for our book reading website and wanted to buy jquery license. However without text selection (which is now available with pdf.js) it wont be very useful for us. We need text selection, text highlighting, and also some ability to embed interactive components in text (like popover when text selected). Will it be possible to add these or are there any plans to allow to add these in future?
How can we help with implementation of these features? Also can you provide some consultation for adding this feature to our website? How much do you charge for the consultation?
