| Release Notes | • Stopped showing the main menu in Basic accounts. Clicking a project in the Accounts list will now take you directly to the Repertoire menu since that is the only module available in Basic accounts. Also, removed the Upgrade button from the main menu in Plus accounts. * Added Settings > General > Interface Level. If you set this to Simplified, some less-used options throughout the app interface will be hidden. If you are an account administrator, you can set this for the other users in your account, but they can change it back to Full if they wish. * Added an All Songs button to the top of the Repertoire menu. This shows all active songs sorted by Title, which was previously available from the default Active Songs smart list. If your account also has an Active Songs smart list in the main menu shortcuts, you can keep it, remove it from the shortcuts by turning off its Favorite setting, or delete it and just use the All Songs button instead. ! Combined the set list view's Edit Song and Edit Layout buttons into a single Edit button with a pencil icon. * Added an Edit Set List option to the new Edit button in the set list view. You can use this to change the songs or the sequence of songs in a set list without leaving the set list view. ! Combined the set list view's Quick Add and Quick MIDI buttons into a single Search button with tabs to search for songs or MIDI presets. • Added Settings > App Control > Actions > Show/Hide Search Window to show the search window with a screen gesture or remote control device. After you start typing into the search field, you can't hide the search window with a keyboard message because the search field will capture the keyboard input. • Added Settings > Advanced > Open Keyboard for Set List Search, which opens the on-screen keyboard automatically when you click the Search button in the set list view. You can turn this on if you more often enter search text to find a song, or leave it off if you more often scroll through the list to find a song. • Changed the icon for the Random Song button to a "shuffle" icon to make it more distinct from the other buttons. • Changed the icons for the Save Zoom Level and Reset Zoom Level buttons on the document toolbar to a small and large document, since the magnifying glass icon is now used for the Search button. • Removed the Action Items button from the top toolbar for Basic accounts, since they can't access any of the functionality that would generate action items. • Turned off Settings > Appearance > Top Toolbar Buttons > MIDI for new installations by default and for existing installations that don't have any MIDI devices or MIDI input actions. • Added "more" buttons (three dots) to the main menu shortcuts for set lists, smart lists, checklists and stage plots. You can click these to go to the menu for the item, to edit or share it instead of viewing it. • Removed the layout options button from the set list menu to streamline the navigation. You can still change the layout while viewing a set list by clicking the Switch Layout button in the top toolbar, or by navigating to Repertoire > Layouts > [layout name] > Edit Details and clicking Set As Default. • Reordered the settings on the General, App Control and Advanced pages to be more logically grouped. • Hid the Personal Transpose Enharmonics setting on the song edit page unless the Personal Transpose is set. • Changed the Shares heading on the event edit page to be clickable to hide and show the share fields. • Added a hint about to the shortcuts page about marking set lists as favorites if there are no set list shortcuts. • Turned on Settings > Advanced > Use New Swipe Logic for existing installations, to make horizontal swiping in the set list view and calendar view smoother and more intuitive. • Updated multi-line text fields to scroll to the cursor position after pasting text in. • Improved the sorting of items whose names begin with non-Latin characters. |
