Text alignment looks like it should be easy enough to add without adding too much to the base size! I've created a request ticket on the project so I can keep it in mind when I'm working on the next update!
I'm so glad to hear that!
And video embeds are all so wildly different that it'd frankly be impossible to handle them all—those you'll unfortunately need to just add using HTML by yourself... Sorry about that!
Ohh I see, I didn't know about this. Well, there are many tutorials on the internet explaining how to do it. I will check those if I ever need to embed something. Thank you for taking your time to explain it.
