I know my comment may sound weird, but that's because I just joined a Lemmy instance* today in order to have the day and month of my cake day sync up with that of my Reddit account.
So far, I didn't spend much time in the default Lemmy Web interface and went straight to Boost after setting up my profile page as I was already using my phone.
One thing I noticed is that, unlike Reddit, it's possible to embed images directly in comments on Lemmy, which took me by surprise when I read a post where someone directly posted a webcomic in a comment without posting a link. This comment, to be more specific. On Reddit, a user would just paste a link to an image which would usually display in the full-screen image viewer on Boost after tapping on that link.
However, I'd like to know if Boost will have an option to hide embedded images (and videos?) from comments and replace them with raw URL links to images (or some kind of placeholder element) that then opens in the usual Boost full-screen image viewer that I'm familiar with.
The only real reasons I can currently think of as to why I'd want those would be to help ease transitions from Reddit to Lemmy, but potentially also for users who are on greyscale e-paper devices and don't want to load embedded images.
Edit: I just realised that Lemmy post titles aren't locked in like Reddit post titles are, so I can edit them! That's something I'm more easily able to get accustomed to.
Edit 2: I forgot to mention that by 'e-paper devices', I mean those that allow users to install and run Android tablet apps (or phone apps in the case of devices with 3-6" displays), like BOOX e-readers and paper tablets. I did actually use Boost for Reddit on my BOOX Note Air2 as I could use a combination of BOOX and Boost settings to make the latter more friendly to greyscale e-paper displays, and of course I backed up and restored Boost settings from the Reddit version to the Lemmy version on all 3 of my main Android devices.
