I just took hours and cleaned up the bug tracker of pcmanfm and did some triage for all of the opened bugs today.
Here are the remaining ones I'm going to fix for 1.0 release.

https://sourceforge.net/tracker/?limit=100&func=&group_id=156956&atid=801864&assignee=&status=1&category=&artgroup=&keyword=&submitter=&artifact_id=&assignee=&status=1&category=&artgroup=557433&submitter=&keyword=&artifact_id=&submit=Filter&mass_category=&mass_priority=&mass_resolution=&mass_assignee=&mass_artgroup=&mass_status=&mass_cannedresponse=&_visit_cookie=411641f74b63b494a940e7e7b370a98d

The other ones are categorized and labeled with 1.1, 1.5, and 2.0 respectively.
Now it's clear what to do for 1.0 release.
Custom actions support for the popup menus is already finished. (experimental and not recommended for daily use yet)
Now I'm fixing some bugs found in file operations and tried to make the file operations less CPU intensive.

I'm not able to give a nice time table or release schedule since I have to find some spare time for coding.
I, however, have did my best to at least define some clear goals for 1.0 release in this bug list.
There will be no change in strings/translations, or UI.

Thank you all for supporting.
