Fixing/Updating the existed GURRIDU JQUERY Grids - PHP/MYSQL

Greetings, I have a developed WEB-BASED MYSQL/PHP DATABASE MANAGEMENT INTERFACE using GURRIDU Jquery grids plugin, please refer to www.trirand.com. There are few points that are missing in the grids I have and they are summarized in these 3 points : 1- I need a default ASC sorting for a column that consists of alphanumeric values. 2- I need an advanced search or custom searching form (fetching values such as dates by a specific range selected by the user) beside the inline search that exists in the grids. Check the CUSTOM SEARCH FORM demo : [login to view URL] 3- Also, Search feature by the operators of greater than, less than for such columns. Check the TOOLBAR SEARCH WITH OPERATOR in the same link : [login to view URL] Important note : Please check the attached document for details. I will reply only to whom had read it. Thank you in advance.
