A useless piece of software when in Google docs, and the worst catch is that you can't even remove it through the add-ons menu. In fact, I am still unable to remove it since it keeps coming back after I 'remove' it from my add-ons list. Aside from that pestering issue, the application's function is flawed from the start. The program points out errors that simply do not exist in my work and highlights my text in a manner that does not even correlate to the suggestions on the right side of the screen. The highlighting of the text doesn't go away after the program closes, which means that I must use my cursor to select the whole document, highlight it a trivial color, and then unhighlight it to get rid of the hideous pink highlights the program places on my text. In addition to the already flawed basis of the program, the application cannot be worked with on an interactive scale; as in you cannot simply click on a suggestion to find where said suggestion is. It's simply frustrating to deal with since I expected more of a professional grammar app that has google docs support, but it has been more of a virus if anything: it simply doesn't leave. If the UI were more interactive and easy to use, maybe it wouldn't be such a pain, but the issue of incorrect grammar suggestions breaks the entire purpose of the application. An utter failure in every degree.
