More formatting options for posts (mainly for broadcasting posts)

Heya, I wanted to resize an image and make it centred but it doesn't look like there's the option to.

Use case is mainly for formatting blogs, made a lil loom, this is the blog I was testing to recreate in the broadcast space and would like the images to fit centre in the page, a decent size so it's not overflowing on the page (great if there's the option to click and image pops up to expand larger).

I liked the 'set description' option, however, my intuition would be wanting to note the source of the image and it'd be great if it could be hyper linked.

Some more Heading sizes and ability to split 2 columns would be awesome too :)

Think my intuition would be to style it like Notion pages (we do most our drafts there) and I had this originally set up for our 'Welcome' post, but realised I couldn't fit the GIF nicely on the side once I went in to post so have removed the visual for now.

Thank ya :)
