Grant Skinner en co. , are serving my every needs as it seems. They are developing a lightweight version of an Component set for Macromedia Flash. The features they are intending to implement which are an improvement against the current sluggy Macromedia components are:

• 75% smaller filesize than Macromedia’s v2 components
• much lower CPU usage
• simplified skinning system
• advanced tabbing management
• Flash Player 6 compatible
• polymorphic with v2 components, no learning curve. In most cases, v2 components can be seamlessly replaced with glic with little or no additional modifications

Let’s hope they succeed :) You can follow their efforts at this site.
