Love this idea. Have been using Xodo for almost a year now and it's been great. Would love to be able to switch easily between different coloured highlights (and other tools) through a customised side bar of sorts. It's a bit of a bother as is, especially when selecting different transparencies.
Regardless, thank you to the developers for all the hard work. It's an incredible app.
