When the user opens an audio file we should store that file name on the project. Later when the project is exported we can save the audio file name in whatever format is being exported.

If the user imports a project and hasn't opened an audio file we should use the file name from the imported project. This is to make sure that if the user opens a project, edits it, and saves it without loading the audio file, we don't overwrite the audio file name.

Convert the current chart, bpms, and song metadata into .sm format

The DB normally initializes the schema using a local .sql file but because we're using docker swarm the file isn't available on the remote machine when we do the deploy.

The obvious solution that comes to mind is to create a postgres image that has the schema already in it, so instead of doing a mount it's just already included.

I can’t import :(

• Remove docker-compose.yml
• Rewrite Dockerfile to use the default /usr/share/nginx/html directory
• Remove tasks.sh

Pasting notes should place them at the current scroll position.

For now, let's just remove any notes in the paste region before pasting, and not worry about trying to merge with what's already there.

For #5, #6 we'll need to know the object position's on the screen. Currently this logic is built into the drawing code. This should get split out so we can calculate the positions ahead of time and use it for both the canvas and UI

The notefield only supports drawing tap notes at the moment. It should also draw holds.

The user should also be able to place holds by holding down the column key and scrolling. When the user lets go of the key the hold should be placed.

With a BPM selected there should be a delete button activate, if the selected BPM isn't the first one in the chart.

I've been looking for an alt to arrowvortex recently and this is the best i could find but this doesnt support 2 player charting. Can you add that please>

The WebAudio API gives us more control over the music playback. For example, we can schedule when the music should start playing, which would help fix an issue where sometimes the music playback is desynced from the chart/metronome.

• Draw the beat line paths in bulk (one beginPath and closePath call for all measure lines, beat lines, fractional lines)
• Resize the noteskin images when the skin or note size changes [1]

When the user presses the backspace or delete key while notes are selected those notes should be removed.

The user should be able to drag their cursor to select a group of notes. If the user is holding down shift or control, whatever is selected should be added to the current selection

If the user starts dragging and scrolls the notefield the selection box should grow/shrink accordingly. In other words, when the user starts dragging, the point they clicked at should be relative to the notefield's current scroll position.

umami is an open source, self hosted analytics service.

umami should be integrated into the existing production docker compose, and exposed through nginx on a public url (http://analytics.openchart.io)

The user should be able to select a note by clicking it. If the user holds down shift or control it should add notes to the selection (or remove them if they were already selected).

Performing a reversible action adds it to the undo stack. If the user presses undo, the change is reversed, and it's moved to the redo stack. Likewise the user can press redo to re-apply it and move it back to the undo stack.

The redo stack should be cleared when the user performs a new action.

• Keep track of actions taken using a stack
• Add a method to Action which undoes the change
• Add a keybind for triggering undo
• Handle undo action
• Add a keybind for triggering redo
• Handle redo action
• Take an inventory of all the things which should be undoable and create actions for things which are missing

This should play a sound when a note crosses the receptor while the song is playing.
