Sometimes during commute, there are some things that can be put together quickly along with images, so ideally, everything can be created within discourse and save to draft. When trying to create another topic, only the previous one is shown.
Since there isn’t a draft feature (like wordpress posts) that can be used to start multiple topics (ideas + images + formatting) and prepare it for publishing, any tips and how to handle this?
You could set up a “Draft Topics” private category. Then move the topic to the public category when ready.
Moving a topic to a new category won’t generate an email/notification for users watching/tracking that category, so you would want to copy/paste the content if you want to trigger an email/notification. (I believe this is correct but you can test it.)
Another “hacky” way to do it would be to create a low-trust account (TL0), post the new topic from that account and then approve it from an admin or moderator account at a later time.
Write a private message to yourself
Thanks for all the suggestions! Will give them a try.
@riking Never thought to private message. Will I be able to then just publish as a regular post or will I need to cut and paste into a new post?
If you have replies in mind, there is a drafts section on your user profile now so they are much easier to find. You can have as many reply drafts in flight as you like.
However, if you wish to create multiple new topics, you’ll still need to send yourself private messages as @riking mentioned; at the moment, only one new topic draft is supported, still.
Is there any plan to support multiple draft topics?
Additionally, for staff this pattern has been formalized in the Shared Drafts feature!
Has anyone considered whether or not multiple drafts could be supported by a plugin?
I think it is a really valuable feature to be able to draft several posts, potentially scheduling them for publishing at some future point without having to revert to hackery…
If you are looking at scheduling posts have a look at the shared draft feature
I think that will work, I’ll give it a try 
Um recurso de rascunhos múltiplos está em algum lugar no roteiro? Todas essas são boas soluções alternativas, mas seria muito bom ter uma aba “rascunhos” integrada onde você possa trabalhar em várias postagens ao mesmo tempo 
Apenas para sua informação, se um usuário estiver seguindo ou seguindo a primeira postagem da categoria para a qual você a publica, ele receberá uma notificação e um link direto para esse tópico, portanto, pode não ser tão discreto quanto você pensa.
