I suggest you to rewrite a preciser review of what your needs are and what you would like to see implemented.
Okay. Basically a built-in IDE that allows php and mysql interoperability.
For example: In the first layout is a splash screen where the user can login or register. The inputs are sent via php to a mysql database. If the user id and password exists in the mysql database the next layout is displayed. If the user is not logged in an error message is displayed.
Register brings up a new layout where the user can create a user id and password and populated into the mysql database.
Example 2: After loged in the user's character picks up a "usable item". The sprite for the item is destroyed on the main window but populates in the items inventory. Likewise, if the user utilizes the item from their inventory the sprite in the inventory is destroyed and that object's/sprite's event is run.
Example 3: User's character takes damage from hazardous object. As far as I have seen in most of the examples so far, the health of the character is maintained in a js file which can be very easily hacked by anyone who knows js. If health/HP level is maintained as a variable in a mysql database and only accessed server side via php, it cannot be hacked by simply changing a js file.
Example 4: User's character triggers battle sequence. New layout opens showing character sprite, moster sprite, HP, etc. (Similar to Final Fantasy 1 battle scenes) User clicks button to attack. Character sprite movement etc. Deals damage to enemy- damage dealt represented in message. Enemy responds dealing damage to character-damage dealt represented in message. HP level decreased. Character deals damage to enemy reducing enemy HP to zero. Enemy sprite dissolves. Victory message displayed. Stat change message displayed ($, Experience, etc...). Sequences back to prior layout before battle scenario layout triggered. New HP/MP/$/Exp variables updated.
Those are just a few examples. What I am suggesting is an IDE implemetation to Construct 2 to quickly and easily add mysql variables and php script. Just as it is easy to add a sprite and set js script events for it, Constrcut should just as easily set mysql variables and set php scripts to manipulate and work with them. (IMO )
