Other improvements: - Added option to save changes to databases (e.g., save comments). - When a database file changes on disk (overwritten by a rerun of DRAMSys or changed by any external agent) the action save changes to DB is disabled, since it is not safe anymore. - Implemented menu options coherence. All actions except for "Open" (reload, close, save, test and metrics) remain disabled until some database file is open. - Created a shortcut to close all: CTRL+Q - Status messages containing a timestamp are displayed in the lower left corner of the traceAnalyzer window when: - User reloads the databases. - User saves changes to the databases. - Any of the open database files has changed on disk.
