Hi,

I don't think there is enough info to exactly reproduce the behaviour shown in your video, as when you complete the task, it does not get a done date added, which means I do not think that Tasks is doing the completion - and therefore Tasks would not be changing the cursor position.

Did you turn off the Tasks setting for adding Done date when completing a task?

Do you have a global filter enabled? If so, what is it please?

[imeed166]

Yes, I have disabled adding the done date when checking the task in the setting.

I don't have a global filter

Here are my settings :

I believe what is happening is that #1103 fixed the cursor position when the command Tasks: Toggle task done is run to toggle the command. All the code for calculating cursor positions is in src/Commands/ToggleDone.ts.

However, when the command is toggled in Live Preview by clicking on the checkbox, the cursor position jumps to the beginning of the line. When toggling a task in Live Preview, the code is in src/LivePreviewExtension.ts - and it does nothing to retain the cursor position.

For developers: there is a write-up of how Tasks handles state changes in:

https://github.com/obsidian-tasks-group/obsidian-tasks/blob/main/CONTRIBUTING.md#how-does-tasks-handle-status-changes

[claremacrae]

For now, if this is inconveniencing you, the workaround to keep the cursor in the same position is to bind a hotkey to the Tasks: Toggle task done command and use that to toggle the task on the line where the cursor is.

I'm afraid this is in a complex area of the code, and not likely to be something that will be fixed soon, unless anyone volunteers to help.
