Splitting on live-mode panes with large notes (especially those with more than 3 dataview queries) results in obsidian freezing up because the new pane containing the same file must be rendered as well. My vault lies at 640 notes, and my daily-notes require 6 dataview tables and one inline query as of right now. Splitting a pane takes 7 seconds. That’s quite long when you do it 50-250 times a day.
I initially thought that the combination of “default new pane mode → editing view” and “default editing mode → source mode” would fix this issue, but that is not the case. The pane mode of a split-off pane does not rely on this setting, instead it is set to whatever setting the parent editor-pane was set to. Source produces Source, Reading Reading and so on.
Allow a setting to keep newly split-off panes empty, or alternatively designate a specific default-note to open.
The only viable workaround I am aware of is to switch the pane you’re plitting on to source mode before splitting.
