SEO optimization

Hi,
I love this plugin, it is very simple to use and in french (and the support is great!), but I’d like it better optimize for SEO. Indeed, I have 19 pages of messages and tags “title” and “description” are identical on all pages. Google does not like that, and these pages will not be well indexed
Could we have for each page, as in the URL, title meta that looks like: title tag – page number
For the description meta, one message of the page would be perfect.
See the next update?
thank you in advance
