* use multiple columns for access nodes if no child has edges
* try to layout close to a square
* layout neighboring accesses to the width of the largest
* increase threshold to hide children on parent activation to 100
* use square layouting in inheritance trees as well
* pass file language from storage to code view
* load syntax highlighting rules files from install directory "syntax_highlighting_rules"
* files must be named <language_identifier>.rules to make syntax highlighting work
* Added new Source Group type SourceGroupCustomCommand to UI and ProjectSettings
* The Source Group executes a specified command on every source file
* The variables $SOURCE_PATH, $PROJECT_PATH, $DB_PATH, $STORAGE_VERSION can be passed
* The commands are executed after all other source groups finished indexing
* The command is executed with working directory set to project directory
* Errors during command execution are shown as status update and in the Status View
* SourceGroupCustomCommand cannot be partially cleared, when one file needs clearing the project must be fully re-indexed
* Enabled errors table during indexing
* Store intermediate errors in StorageCache
* Open tab for errors if no tab yet
* "Show errors" for file disabled during indexing
* Hide indexing dialogs with ESC instead of stopping indexing
* Fixed indexing can be interrupted when dialog hidden
* Clear intermediate storages when interrupting
* Abort waiting for less queued storages when indexing interrupted
* Don't index another file when indexing was already interrupted
* Moved indexing interrupted progress dialog to TaskBuildIndex
* Use MessageIndexingInterrupted instead of MessageInterruptTasks
* Added tab bar to top of main window with UI/shortcuts similar to web browsers
* ComponentManager offers components for 2 use-cases: application and tab
* Application components: log view (status/errors), bookmarks, screen search, status bar, tabs, tooltips, dialogs and all tab views disabled
* Tab components: graph, code, history and search
* When a project is loaded there is always at least one tab, otherwise there is none
* Each tab replaces the application views of the same name in the main layout when activated
* Each tab has it's own TaskScheduler, to process tasks independent from other tabs
* The application has a global TaskScheduler for application wide tasks
* The singloton class TaskManager is responsible for managing the TaskSchedulers
* MessageListeners and Messages hold an optional schedulerId, both must be set to only send to a specific TaskScheduler
* Bookmark buttons where split off into a separate view per tab, bookmark managemement is done in the application
* History menu processing is done by the QtMainWindow now
* Screen search is an application component, the responders are always changed to the active tab
* Plugin messages are opened in a new tab
* Symbols can be opened in a new tab via middle click/context menu in graph, code, history dropdown
* Full text index creation is mutexed now in PersistenStorage to make it fully thread-safe
* All tabs are closed when switching projects
* Tab contents are only animated when visible
fortune cookie message = Catch your lucky star!
* don't use thread::detach() in TaskGroupParallel::terminate to make it useful for tabs
* properly terminate TaskFillIndexerCommandQueue
* fixed wrong microsecond delays
* moved some task delays to TaskDecoratorRepeat for better transparency
* use in local index building during refresh
* use in read cache building on project load
* use in some storage access requests
* also slightly improves speed
* fixed undoing to multiple actives didn't show all nodes in graph
* fixed wrong name in search bar, status message and history dropdown
* fixed flicker when activating multiple nodes in code view
* Fixed TaskFillIndexerCommandQueue exiting right away when all commands fitted into queue on first call
* Fixed TaskBuildIndex exiting right away when starting of indexer processes takes longer than the update cycle
* Refactored Indexing Tasks Behavior Tree
* Pass NameHierarchy to record new symbol returning an Id
* Cache symbol Ids in Parser implementation
* Reuse symbol Ids as reference when recording related data
* Pass FilePath to record new file returning an Id
* Cache file Ids in CanonicalFilePathCache
* Store file Id in ParseLocation instead of FilePath
