Note : This extension may not work on builders that are still using Android Support libraries (Like Kodular), because my extension works on
And for @Anke's request, I am glad to say not only text size, color, can be adjusted but, filters, typeface is also customizable

Cool extension will be better after these updates
Ingenious, but this can be achieved easily with just blocks.
The android Library used in this extension :
(This is customized fork of an android lib)
Extension sources :
But with this extension it can be achieved using 1 block... 
If someone bans on making an app with a few blocks, then yes. For me it does not matter if a function takes 1 or 20 blocks.
But the fact is, if someone has a problem with coding in ai2, it might help.
You are right but this extension may be helpful for the new users or who are beginners or do not want to code the blocks
If they do not want to code the blocks they shouldn't start using App Inventor 
Also it is benefitial for large scale project 
Sorry to make this comment but - have you ever used a typewriter? The paper should start at the bottom of the screen and feed upwards for each new line of text.
See my website for a block code snippet download:

No problem, you just want to improve me 
Sorry for the mistake but, my library had this effect only
