Extend the capabilities of the timeline marker

Many software have bookrmars with a bit more features than just a single position and a name, which we could have a look at to identfy nice things to add to Blender's

. Davinci Resolve can associate colors and tags, which themselves can be used as filter for other usage like frame jumps or writing chapters in exported video files metadata.

The way you make marker is just clicking a button, it creates a one-frame marker with the default color and no name, and you can double-click a marker to open the editor and add extra flavourings:

Animbot's time bookmarks is another example of bookmarks. Click the button to make a one-frame marker, or select frames to make a marker on the selected frame range (Maya can select frames in the timeline).

Though Maya finally got its own bookmarks recently, and it's pretty good too.
You click the bookmark button to open the bookmark creator, which you can type a name, frange range and color. It will automatically use the frame range if you select a bunch of frames . Markers can also be used to change the time slider frame range, it's really handy if you need to spend time animating a specific range of your animation or make several renders with different frame ranges: just frame the timeline on the corresponding markers.

Both animbot and Maya have a bookmarks manager that allows to manage marker in bulk rather than opening an individual marker's settings.

Overall, we can note a few features that could be interesting in Blender which i like to rtegroup in three categories of usage

Personal Organization

• a start and end frame
• color
• label
• keyword
• notes? maybe overkill

Management

• a single manager that opens when you click Add Marker that goes away if you click away and doesn't block further actions, so that you can quickly create one marker and move on.
• a bulk manager that stays open as long as you don't manually close it, so that you can both make changes on many markers but also keep making new markers very quickly without having to re-open the menu all the time.
  Table-like design, with tab/ shift tab to navigate columns and enter / shift enter to navigate rows are very efficient for that.
• Be able to drag marker start/end points the same way we can drag single-frame markers

External Use

• a popover to filter which markers to display / allow jumping - either by keyword or color
• option to export markers as chapters when a compatible video container is output.
• Be able to frame the animation editors on a marker, as well as change the temporary or scene's start/end frames (bonus: add that function to command line rendering for easy headless frame range partitioning)
• Why not finally a proper visual tool to handle camera markers?

Is start the marker in this image? How would that interact with binding cameras to markers, what are you using markers for in Blender now? etc.

Can you mock up what you would want the Blender one to look like
