What's new in v0.5.8
Move a group of notes along the timeline, a bigger current-frame number, and an Open Folder button.
New: move several frames' notes at once
Hold Shift and drag across the timeline to select every note and drawing marker in that range, shaded in translucent blue, or Shift+click markers to add or remove them one at a time. Drag inside the blue band to slide the whole group along the timeline, like keys in Maya's time slider. A label shows how far it will move and where each marker will land. Every frame keeps its own notes and drawings and the group keeps its spacing; hold Ctrl as you let go to copy instead. The whole move is one undo step, and it works whether Drag Markers is on or off.
New: large current-frame number
The frame number beside the timeline is now large, bold and yellow, with FRAME # underneath. Click it and type a frame number to jump there, as before.
New: Open Folder
A new button beside the clip name opens the folder of the clip playing in the viewer, with the clip selected, in Windows Explorer. The folder icon at the top right now selects the clip too.
Also recent, from v0.5.5 to v0.5.7
- New ATK icon: the interlocking ATK logo appears on the window, taskbar, Start Menu shortcut,
.atkprojproject files, installer and welcome window, sharp at every size. - Notes PDFs for a whole playlist: File → Export Notes PDFs for Playlist… saves a Notes PDF for each clip you tick into one folder, named
<clip>_review_notes.pdf. - Save confirmation: Save and Save As show Saving… and then Saved name.atkproj at the time in the status bar.
- Add Existing reviews: the Review Library's Add Existing… button lists
.atkprojprojects you already have, and opened projects are listed too.
