A suggestion for a post category called "DevLog"

In the category of "DevLog", people will post the progress of projects that they have been making. It's probably completely useless because the same thing can be done with the "Project Sharing" post category or even the "Off Topic" post category or the doc project section. But it would be cool to see how a project grow in time, how the developers overcome difficulties. Idk

Like you said, I think the best solution is to have a devlog post in Project Sharing or Off Topic with a reply for each devlog entry. However, if you want people to be able to play the project at each different stage in development, you can export the project for each entry and upload it to GitHub pages or something similar for download.
