never used mint. how does 'show all desktops' look like ?

It sould be able to be opened through the hot corner.

The Deepin filemanager doesn't really support split screen mode but you can do it yourself.
Looks like that: http://www.freeuploader.ml/?filename=UkdWbGNHbHVRbWxzWkhOamFHbHliV1p2ZEc4eU1ERTNNRFV4TWpFME1qSTBOQT09_png
Simply open it two times an drop the first window to the left screen side and the second to the right side.
Alternatively you could use Nautilus (apt-get install nautilus)

you can easily show all desktops and switch between them by using the key combo: Super+S+arrow keys.

easier than using a corner.

@all
Thanks for the response

correct. That's what I meant.

@nipos
That's exactly what I tryed but it's not very user friendly.

@gunnydeepin
I disagree, it's not easier. You have to get your hand of the mouse to press the arrow key (if you are right handed).

this is 'multitasking view' actually. we'll consider add support in hot corner.

Maybe you should redesign the API so users can put what they want to the hot corners

设热区的界面又不受我控制，里面加个配置文件不就ok了。。。
