Sometimes I am not entirely sure if the last stroke of an character really is the last one. This sometimes leads to the situation where I am not finished writing a character (in my head) and the app automatically goes into "writing complete"-mode, and I´m like "huh, oh right, that actually was the last stroke". What I would like to see, esp. in raw-squigs-mode, is an optional button that you have to press once you think you have finished writing. If there are strokes missing, the app will hint the next stroke upon pressing the button and lower the grade. Otherwise it will go into "writing complete"-mode.
PS: An example: Consider one has trouble differentiating the characters 问 and 间. Now the question for 问 comes up, and the person is prepared to write it as 间。 The app will never know that the person intended to add another stroke.
