I like the inclusion of the drawing feature in app, especially for gutters, but it definitely needs a few extra options. With these additions I could easily see myself switching over from another CRM I have.
1. Straight line feature so I don't need a ruler.
2. Customized symbol additions. For example, if I am working on a two story roof I can include custom symbols I have drawn beforehand to quickly add in, like a ^ symbol to indicate 2 stories or something similar.
3. Double lines, similar to stright lines but double parallel ones to indicate whatever you need them to.
4. Different sized lines.
5. Text box additions.
These are the things I could see make this my all in one system if they could be implemented.
