Yeah it’s Ctrl+D. I do use bookmarks on occasion (especially for stupid websites with non-intuitive URLs and page titles I can’t easily find by typing in the omnibar), but not as a way to organize my work.
The reason I mention ADHD for this in particular is I saw a home organization tip for ADHD that I related strongly to: ADHD brains really benefit from having everything spread out on a table, visible and immediately available. Trying to force an ADHD person to constantly put things away is super counter-productive even if it’s apparently good advice for neurotypical folk. Though of course ADHD is not an excuse not to clear the messy table once the project is finished.
My computer desktop follows the same principle. I’ll have as many workspaces as I do ongoing projects, and every workspace has all the tools I need open. And the good news is it’s much harder to run out of virtual space than it is to run out of space on a real table.
It can do both, lossiness is toggleable.
If you’ve seen a picture on Lemmy, you’ve almost certainly seen a WebP. A fair bit of software – most egregiously from Microsoft – refuses to decode them still, but every major browser has supported WebP for years and since superior data efficiency compared to JPG/PNG means is already very widely used on the web. Bandwidth is not that cheap.
