pack window before accessing its geometry;

always refresh font metrics, to help window size calculation (amending 2585c81d840a);

more precise tooltip window size;

take component width as indication if it is already visible/layed-out, to avoid multiple formatting with minimal margin;

reset active area for outdated snapshot (again?);

some support for implicit senback, meaning that it uses the caret position instead of explicit command exec_id;

more abstract Sendback operations, with explicit id/exec_id properties; purge result messages (again), cf. db58490a68ac, 7b61a539721e;

some support for breakable text and paragraphs; tuned Symbol.scanner, which operates on symbols, not characters;

tuned names

removed (unicode) tooltips: can not adjust font in basic swing tooltip

delayed search to improve reactivity

respect font property for symbols

capitalize lowercase groups; tuned with mkString

more generous timeout for SML/NJ, which is approx. 40-80 times slower than Poly/ML; more generous timeout for HOL-Quickcheck_Examples, which is rather slow in checking its examples (and mostly sequential);

Countable_Set: tuned lemma names; more generic lemmas

enable Symbols dockable by default;

tuned;
