Issue 1-2:
Once hovered over, the tooltip would seize the focus and block the typing from then on. I have to switch away and back (e.g. via Alt+Tab) to let EmEditorView regain the focus. Clicking in EmEditorView could break the snippet processing.
So is it possible to set the tooltip unfocusable?
Issue 2:
Move mouse from Find (Quick Launch, etc.) dialog to the main window.
EmEditorView will not get the focus (i.e. no text cursor blinking).
Issue 3:
Open a file in a new window.
If it prompts (for newline-inconsistent or encoding), the dialog could be blocked by other windows, especially when X-Mouse is enabled, or there is an always-on-top window.
So I hope the Taskbar button will be present in such cases, to let the user know there’s a window. This is not only for X-Mouse.
