A feature selection of a feature of an application may be received, where the application is designed for partial execution on a server and for partial execution on a client computer connected to the server by a network. A current location of application code implementing the feature may be identified as being at either the server or the client computer. Then, implementation of the feature may be relocated from the current location to a modified location, where modified application code, obtained from the application code, is re-assigned between the server and the client computer.
