Thinking about enumeration design. Probably it would be better to only use index search when doing recursive search for enumerating a directory, and do a direct search when only traverse the first level. @jjw24 what do you think

I think directory recursive search with Windows Search could be restricted by user's indexing options/excluded directories, so allowing an option to use DirectoryInfo search method is preferred per current design in this area.

What do you mean by direct search when only traverse the first leve?

oh I mean we may always use the DirectoryInfo Search for the non-recursive traversal.

@onesounds mind creating a engine selection ui for this? I am not sure whether it is a good practice to use interface for purpose selection, but probably we can adjust that easier.

@Flow-Launcher/team I have almost finished most features and the UI Refactor. There're some small features in everything plugin that I haven't ported, but it will be fairly easy to do so. Anyone want to give this pr a check?

Changing action keywords do not take effect on first try. Repro:
Remove the settings.json file in user data directory. Start up flow, go to Explorer and change Path action keyword. Trigger the keyword and it does not happen. Only after changing the action keyword again then it will trigger.

2. Bring this message back when Windows Index is disabled:
   

3. Hide the search window when the prompt to install Everything is shown:
   

4. Please add icon for this result:

@taooceros I am fixing 2,3,4

the concurrency bug is ....very weird but interesting (I know what's causing it, and try to find a good solution).
Basically the Wait is cancelled so the semaphore count is not reduced, but the finally block release it.
