Version 1.1 contains support for macOS. Only one purchase is needed to gain access on your iPhone, iPad, and Mac devices. Other features and bug fixes: • Photos can be dragged and dropped into the text editor. • Menu bar support added to iPad. • Images now render in the PDF export preview. • The text renderer, when using split view, no longer flickers when making edits. • Added a custom category in the insert tab. Users can now put in frequently-used text, which syncs via iCloud to all your devices. • Fixed a bug where the renderer sometimes didn't load in split view, when moving quickly between different files. • Files in sidebar folder directories can now be sorted. • Fixed keyboard shortcuts not working. CMD + Y is added to redo an operation. • Both the editor and renderer now remember the location when going between different files.
