Totally agree, Pete. I am located in China and DTube doesn't work that well for me (it has gotten much better though) due to my internet. I'd love to be able to upload videos at a certain time and then choose when to make it public. The same can be said about Steemit as well. For someone without a huge following, timing is very important in order to get noticed by someone with SP and can make a difference between earning hundreds of dollars and just a few cents.
If we have the unlisted option, then I could upload at a time the internet is working well and then actually publish it at whatever time I want.
