Suggestion: Longer <TITLE> tag in Element Web

### Your use case

#### What would you like to do?
I'm running an SEM Rush "audit" on my site and it's flagging my element-subdomain for not having "enough text within the title tags" - e.g:
`Element`
 
#### Why would you like to do it?
This seems to be a missed opportunity - can quickly roll out a significant change SEO wise:

#### How would you like to achieve it?
Change it to something like this:
`Element - Decentralised, encrypted chat & collaboration powered by [Matrix]`

Edit: It looks like this page is also missing an H1 tag, possibly another "easy SEO win"
