Modals don’t work for me neither… and the edits reflect on below object bug frustrates me even further 
What makes modal hard for me is the inability to reference more editor/block/object. A smaller modal might work. Sidepane and tabs are definitely what I like to reference the whole object.
The other constrain is that modal as quick access is not accessible anyway. A command to open pop-up at anytime will probably make modals better. However, I like command palette or line way more. Just a single line for quick add and it doesn’t block out anything.
FR Obsidian command palette
FR Tana command line ← Maybe I prefer tana version more (but haven’t used it)
PS slash command (notion style) is not my thing because it locates within the contents which interrupt my thought flow: content part of mind, and action part of mind (always temporary in note-taking app)…
