I have trouble remembering to assign categories to my CSBlog posts as the AdvancedPanel of the PostEditor is located below the post button and is not visible. When I don't see the categories checkbox I forget to assign my posts to one. I wanted to make sure my posts were assigned to categories, pllus I want to expand on categories and add series collections (subcategories) like on my dotText blog.
The 3-second fix would have been to keep the AdvancedPanel open by default, but that was inefficient. All I wanted was a Categories panel on my EditPosts page, so I added one. I then relocated the Categories checkbox control from the AdvancedPanel to the new Categories Panel and set the panel open by default. Finally I moved the post buttons below the panels.
A screenshot is worth 76 words. Red arrow to the new categories panel, green arrow to the existing AdvancedPanel, buttons below. It took me longer to post about this mod than to actually do it. Once again, everything was there in the framework. All I had to do was type. Here is the zipped mod.
