I use this every day for checking Google files for course content, but there are three problems I encounter multiple times per day. I use Grackle Slides mostly and these issues pertain to that. The first, which is the most bothersome, is the software getting hung up when I recheck a document. I have to close and relaunch the add-on every time I want to recheck a document. The second issue is that when it has checked the document and finds images that need alt text, using both the alt text shortcut and the option from the menu bar, Grackle Slides crashes. The third issue is that there's no easy, fast way to tag an item from the list of document issues. It takes so long for the software to respond when trying to tag images and objects. It would also be helpful if things could be edited or deleted from the page tab. As an example, if there are empty text boxes, I have to click on the error in the Grackle Slides sidebar, highlight the empty text box in the presentation, move my mouse into the presentation and delete the textbook from the Google slide. In sort, it's slow, inelegant, and crashes frequently. If those three things weren't a constant obstacle to my work, this would get 5/5 stars.

Would be nice to be able to review the warnings and mark them as not appropriate, mainly because many are just bugs of the tool, like for contrast. The error about lists is also an error of the tool. Even if the Slide Structure tab does see there are several lists, it still says we have to merge them. No, a slide can contain several separated lists.

Won't let me correct errors. Keeps indicating it can't load file, and forces me to reload and restart process.
