I'm a big fan of fighting with Drupal's inefficiencies and bottlenecks. Most of these come from contrib modules. Everytime we install a contrib module we should be ready for surprises which come on board with the module.
Drupal Views offers us a cool feature: ajaxified pagers. When you click on a pager, it changes the page without reloading the main page itself and then scrolls to the top of the view. It works great, but sometimes you may encounter a problem: if you have a fixed header on your page (the one that stays on top when you scroll the page) it will overlap with the top of your view container thus scroll to top won't work preciselly correct and the header will cover the top part of your view.
It appears that Django Taggit doesn't support transliteratable tags, what we need to do is to add such support, how you may ask? We should use proxy models. Just add this piece of code to, let's say, ru_taggit.py file:
When Solr Thumbnail (https://github.com/mariocesar/sorl-thumbnail) returns and error like "SuspiciousOperation: Attempted access to '/media/products/505.jpg' denied" or Bad request: 400 you need to check the path of the image you want to resize: it shouldn't start with your MEDIA_ROOT like '/media/products/505.jpg'.
