Make placeholder more useful

[juliushaertl]

We could advertise more features in the placeholder text, similar to google docs:

Screen.Recording.2023-08-01.at.13.41.04.mov

Currently we only have a hard coded message:

• Add notes, lists or links ...

Examples from other products:

• Notion: Press 'space' for Al, '/' for commands.
• Talk: Write message, @ to mention someone ...

Topics we may advertise:

• Smart picker
• Mentions

Any thoughts about this @nextcloud/designers mabye also ideas of further features to advertise through this? I also thought about specific smart picker features depending on what is installed.

Yeah, that seems good! Do you have an idea for a message you would like? I’m not sure the message switching around would be accessible, so it’s probably best to start with a single one.

Start writing, or try '/' for the Smart Picker
