hmm not sure about the block icon, I think it's not too clear 🤔

I find it quite fitting, also considering the other icons we looked at this week

@marcoambrosini I find it fitting well, given that it shows a box with text inside - which describes text boxes pretty well. Do you have an idea for an alternative icon? And are you against the icon or just not 100% sure?

I like it. I'm not sure about the 'no heading' icon with the two T though. If the text is not bold the icon is just deselected and does not change to a thin 'F' either. Same for the lists. If no list type is selected the icon still displays a list and not a 'non-list' state.

I implemented it as it was once decided in #2836. I think the idea was that it's a more generic icon to communicate "text size" than "H1". I don't have a strong opinion on which one communicates better. "H1" might also be hard to understand for non-english speakers. Maybe designers can comment here @marcoambrosini @nimishavijay 😊

I find it:

• too similar to lists > difficult to quickly find
• Rectangle shape similar to neighbouring icons > difficult to quickly find
• reminds me of left-alignment icon > possibly confusing

Maybe brackets are good for this case?

So I would go with:
https://fonts.google.com/icons?selected=Material+Symbols+Outlined:data_array:FILL@0;wght@400;GRAD@0;opsz@24&icon.query=parenthe&icon.size=24&icon.color=%235f6368

Brackets I would find to easy to only associate with a code block, not sure this is a good one for average users as well to refer to as blocks
