Feel free to post anywhere you want. Basically, everything related to the device goes to blue categories (design and features). Orange is off-topic, like introductions or just chit-chat (we always appreciate that if it's something related to tech industry, as it's a good way to generate new Eve ideas). And then there's the "what's next" category where we discuss future projects from Eve. So if you have any thoughts on what should be made after we finish the PF, feel free to post them there.
By the way, if you have a new idea that hasn't been noted anywhere else, you should either create a new thread or post them in this thread:
It's easier to track all the suggestions that way
And keep in mind that all the categories are open, you can post anywhere - except maybe the announcements category. But even if you post there, we won't kill you haha In the end, this forum has different permissions, so you shouldn't be able to post where you're not supposed to post.
