We have started to create relational and transactional InnoDB database at first, but researched showed that hosting mostly support MyISAM. This would be a problem.

We will watch future direction.

If you are looking for documentation on template development, we have a basic description of template system and extension development in below link:

http://www.abantecart.com/document_wiki/index.php/Developing_Templates_as_Extensions

We recommend to follow template development as extension to keep future core upgrades easy.
You can follow template2 free extension (posted before) to get an idea how to develop template extension.

This is a valid future issue. We can build directories/files with the same approach it is done in resource library. Noted.

It is already available in AbanteCart.
In the product, category and manufacturer (brand) edit section there is a SEO Keyword that needs to be set.

You need to have .htaccess enabled as well for this to work.
