EasyEyes VS TataruHelper

Secondly, Easyeyes is another tool useful for filtering what fx you see and don't see. Unfortunately I believe you need to actually see the fx for the easiest way to disable it, so it would be very awkward to do on the fly, but it still may be of some use to you.

There is a plugin called EasyEyes for FFXIVQuickLauncher that is able to remove VFXs ( the flashes and animations ) on demand, maybe she can use to filter those?

Tataru Helper, yeah.

As for a plugin, I noticed a github link in another reddit thread that seems to a combination of a text hooker, selectable translation resources, and an overlay for just displaying the text that was extracted + translated. I haven't used it personally, but it might fit the description since it just separately displays the translated text instead of messing with the in-game UI/texts.

My husband's first language is Russian and he uses this app called Tataru Helper to translate the game. It's made and mostly used by the Russian-speaking community but supports many languages using machine translation. It's not always perfect, but better than nothing if you don't understand English.
