very amazing feature! but may I suggest adding a short-cut for activating market instead of just mouse click on the icon? Thank you.

Works as advertised. It allows marking Pages with any number of colours, either from a pallet or custom defined (RGB). The pen has opacity/transparency control, as well as size. I missed a way of marking straight lines, like most drawing applications do (e.g., pressing SHIFT to move the pen just in vertical and horizontal lines), but, otherwise, it works well.

love the sleek ui! here's some suggestions:
- add the mouse mode to the mode selection menu
- add a text mode where you can write text

It's great, but can you add a thinner pen size please?

Estaría bien que usase menos la CPU para funcionar, pero es simple, esteticamente bonita y muy funcional. Útil para presentaciones. Y poco intrusivo :D

For years, I have been taking screenshots to share with people, but always needed to edit them in a photo editor, so I could circle important things to draw attention (in the screenshot). This tool bypasses all that, allowing me to do so within the browser, and then easily take a screenshot.

It is only missing a highlight function. If that were to be added, then this would be perfect. But still, this is a must-have if you work in support or generally need to share screenshots, while pointing out things to people.

Well done.
