I'm a bit of GIS rookie but I seem to have found my way around most of the intermediate functions of QGIS that I need for my work over the last year or so. What I want is really simple, but multiple searches have returned nothing. I'm using a base map from quick map services and I want to be able to manually trace over all of the water courses in a certain area in order to highlight them as well as annotate a number of other features such as location of assets etc. I know this can be done in the print composer but I want to be able to add it as a layer so that I can produce multiple prints of different "zoom frames".
Is there a tool that I'm missing that allows you to manually annotate and add as a layer; essentially paint in GIS 2.14.2?
I'd also be interested to know if there is a layer already out there for mapped watercourses in the uk.
