When I try to use Glitch’s coding interface, there is a permanently animated UI element by the Tools menu, the Logs option in the tools menu, and the sidebar in its collapsed state, which I find very distracting and undesirable when trying to write code. Despite being small and relatively slow-moving, this is still an accessibility issue (see for instance https://webdesign.tutsplus.com/tutorials/a-guide-to-creating-accessible-animations–cms-32038, https://webaccessibility.asu.edu/articles/animation).
Other animations on the website, such as when loading a project, cause similar problems but are easier to avoid since I don’t need to interact with these pages.
Please allow Glitch users to turn off these animations, or (preferably in my opinion) just remove them entirely. I understand that Glitch wants to be an inclusive & supportive community, and accommodating your disabled and neurodivergent members will be an important part of that.
