I’ve been looking for a solution to do Kanji Drawing input on my computer without needing to switch between Google IME and Microsoft IME’s toolbar, and just had an epiphany: Windows Touch Keyboard has the handwriting panel, making it a great way to input drawn Kanji.
To enable it, Right-click on the taskbar and select “Show Touch Keyboard button”. Click on the Touch Keyboard button, and on the top left of the window click the options button and select the Handwriting icon. With the 3 dots button you can select the input language.
It’s a bit of a pain to use with a trackpad, but would be really useful with a pen tablet/touchscreen.
