Good idea, but completely useless for me because this on-screen keyboard has the English keyboard layout.

The add-on performs quite well. When typing multiple words using Google.com or YouTube search bar. If you make a spelling mistake and try to click between the words to correct it, pressing the "Delete" button always erases characters starting from the end of the last word, rather than from the cursor's position. Additionally, it would be helpful to have an option to pin the add-on to the toolbar. This way it would be easier to enable and disable the addon when needed. Thanks.
