Can you add a 'document toolbar' (file open list) in Writer, like in MS Office Word and Atlantis Word?
I miss at least an extension of the number box in navigator (F5). Better will be a full sticky (last) session list. aka document toolbar. It looks mighty old that such a feature is missing in Writer.
As pointed out, this is not the proper place to make feature requests. But for the sake of discussion and getting more users interested in what you are asking for, I ask the following.
Could you provide some links to documentation about this feature, as it exists in other software. Also if you can find any images of the user interface that demonstrates the appearance of the feature then include that as well. You may also write a concise description of the feature, it's intended purpose, how it functions and a motivation to why this feature is so good to have.
