v2.3.3

• Various improvements in dealing with large emails database (#110). The app now works more stable with accounts that have more than ~5-6k email messages in the case if the local store feature is enabled. On the first run, the app will convert the local database format which might take some time depending on the database size.
• Allow disabling the page rendering GPU acceleration process creation. Enabling this option will allow you to save some memory but will likely slow down the page rendering process somehow which is normally not a huge concern. The amount of saved memory is directly proportional to the number of accounts added to the program. The option is disabled by default.
