1. I think you would have to recode a bunch of things to do that but I will see if I can keep that in mind for the next version. I’ve been working on making a WordPress plugin for this which is going to mostly be a total rewrite so I should be able to incorporate that in if I can remember to.
2. While description and title are still used keywords meta tags are not even looked at by many search engines anymore, including Google. https://support.google.com/webmasters/answer/79812
3. OK I will test this out and see what I can figure out.
4. I was thinking you were referring to actually selecting a grid since you can have multiple grids. But now it sounds like this is the same thing as #1. I haven’t been adding new features to the 2.1 version lately and have been concentrating more on bug fixes for it and the new WordPress plugin which isn’t yet available.
