RT IDEAS  I tried the demo and hoped for better results out of the gate. It had minimal effect size-wise on a 9MB file--9.07MB down to 9.02MB-- a 0.5% reduction. Invisible buttons (with Glow filter) became black objects obscuring the graphics below. Text that was converted to outlines became blobby.

Trying some settings changes, I was able to drop the 9MB file down to 4.6MB, but that seemed mostly due to sound compression. It still had the graphic anomalies above.

I can tweak sound externally for similar results.

According to their site, the $99 version is for personal use only. To use it commercially, you need to purchase the $299 version--actually worth it to me if it worked out of the box and significantly reduced my bandwidth for my larger projects and less time having to tweak my work.

I see potential, but no use for me at this time.

I started programming with 3.5k of usable memory on my VIC-20. The MU logo on this page is 4.8k. Optimization is always in my thoughts.

RT IDEAS  The sticky notes worked fine for me in version 3 of the lastest build. You have to click something to select it to deleted it, why not click and drag in one move to delete it anyway?! IMO it seems like a bit of sour grapes to rate it one star for something trivial.

You have to click an empty gray area to change the toolbar. If you have the ruler shown, you can click the empty area under the tab stops selector or drag the notebook wider.
