Describe what you would like to have

Adding extra command line options for "cm" to speedup initial display of relevant information:

• a "scroll to end" instead of displaying the top of the log, chipmunk opens from cm scrolled to the end of the log (or ideally an arbitrary line number, positive numbers being from the start, and negative values denoting the number of lines from the end, scrolling to end would thus be "-1")
• a window ratio, for instance if specifying 30%, the log view would take 30% of the screen vertically, and 70% would be for search/details/history/chart area
• a full screen option, when set chipmunk starts in full-screen instead of windowed
• a chart option, when set the chart tab is visible by default (instead of search tab)
• an extended filter option, command line allows to specify filters, but their color is automatic (and being able to explicitly set background and foreground would be preferable to chipmunk determining the other color by itself)

Potential Workaround

Currently all this can be done (except filter colors) but it requires clicking
