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.

10/10 clean UI, easy to use

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.
