When you add pages to a website, Odoo automatically generates a hyperlink based on the chosen title. But to the SEO needs, marketers would ask you to make the urls correct. For example, to make them shorter or to include key words.

The app website_url_friendly solves the task (read about the author and download it here). Now you may change a web address through the metadata section. Open 'Promotion' and indicate a new page URL.   

Tests were conducted on Odoo, version 8. IT Libertas developers have added a special check, when a shortened URL is received in controllers.

Be cautious: the module seem to be not compatible with multilingual sites

Standard Odoo set already provides with a well-functioning scheme of messages' interchange and storage. Letters are distributed among objects and are structured in email threads chronologically. To ease reading, the software also deletes excess elements (quotations, signatures, etc.). That's useful, but sometimes makes understanding of texts impossible.

The app mail_full_expand is to overcome this difficulty. Push a button and you would see the message details, including its source without 'sanitization'. Besides, with a help of this module read long letters comfortably.

In order to specify a color of interface elements, it is required to enter a 7-chars-long HEX abbreviation, which has been found previously. You may avoid these hurdles by using the web_widget_color tool. This app allows to select a color with a mouse click. Moreover, as soon as you save an object, Odoo would correspondingly illuminate a field.

For developers.  Indicate widget='color' in an xml field of the type 'Char'
