When casting on Chromecast, would be nice to have a laser pen feature so I can point to things on my tablet and students can see on the projector, instead of using pen or highlighter.

Goodnotes app on iPads have this laser pointer/trail feature. It is very useful to draw the attention of the audience while presenting something on the tablet: handwritten material or an imported PDF.
Drawing on the screen will add a laser trail, which will dissappear after one second, allowing you to highlight larger areas or add temporary annotations to the page to guide your audience's attention.

When you use a pen there is an Option from Android to do that

A mouse is not really practical in a classroom, as I use the tablet so I can be mobile in the classroom and still write and teach using Squid as a SmartBoard. And a laser pen is needed, as I am usually not at the board to point to it on the board.
La idea sería poder rayar y recalcar cosas con el, para que se borre posteriormente

In the meantime, you can use a mouse. Many tablets allow you to connect a mouse to get a cursor on the screen.
