We are building an application which will contain spell checking features for areas where users will enter input.
We have already implemented the feature for our rich text editors, whereby spell checking can be turned on and off by using a toggle button.
We are now considering whether we should enable spell checking for things like text input fields or the "tags" input widget on the stackexchange sites, where users are only expected to enter a small amount of data.
Will this feature be useful and not annoy users at the same time? To reduce clutter, we are thinking to NOT include a toggle button to turn spell check on and off for text inputs and tag input widgets.
Do users tend to react well to spell checking?
