Improved Template Search filters

With greater than 50 + templates to administer and update, I locating and updating a subset of templates is time consuming. Having a easy way to filter templates by folders available on the template page would help me easily locate templates. A template report is available for on all templates by date created.  I compare the report with ones that were updated.  Also adding a search filter by templates updated greater than would also be helpful.  As the number of templates grow, the slower the page loads when you choose 50 templates.  Lastly, i am only able to upload one template at a time, does anyone know if there is a way to upload several templates at the same time?
