1) dDoes exactly what I hoped forwhat it's intended to do, tested while running configure on a bigger in-tree build project like CodeBlocks with KDevelop configured to monitor directories for and reload them in case of changes(e.g. Not profiled formally,CodeBlocks).
Dir watching works also on Mac if you don't set watches on all files; the effect of reload-limiting is clear from following CPU usage in top, from fan noise, and from the rRunController buttons not turning on in the toolbar for only short periods of time.
2) tested on Mac and Linux. Works as expected except for the fact that the initial project load puts TWO entries in the "stop individual job" dropdown menuTested on Mac and Linux. There are no duplicate proxies as far as can tell so this escapes me still.
