The process of increasing its size might lead to lost signals. 99% of the time, setting the size at startup to a larger value than the default (before anything but the input semaphore is registered) is a better approach than increasing automatically, and in the remaining 1% it is better to fix whatever application issue is causing semaphore leaks anyways.

Re: [Pharo-project] Pressed Morph feedback on PharoTheme

I think this is when the button has a true state, as used by the getStateSelector of the morph. This is visible in the Hierarchy/Flat button in Nautilus, where Hierarchy is state == false, and Flat is state == true (and has the blue color). In the case state true, PharoTheme may be falling back on the colors of the WateryTheme. Another bug shown with my change is, if you start to scroll with the slider, it depresses correctly, but, as soon as you move outside the bounds of the scrollbar, even while pressing the left mouse button, then the slider goes back to the "not pressed" state while you are still scrolling up or down. >> Side note about UI changes in Nautilus: will there be any changes > about the Groups/Hierarchy/Class/Comments buttons ?

The downside is that it tethers you to the network if you happen to need access to the proxied ancestry.

check the HOWTOBUILD file in the git repository + there is an image.sh script in the /image folder of the git repo I think the git repo should be the place to keep track of such documentation!
