Sorely need this feature to work as welljlnsrk wrote: ↑Fri Nov 08, 2019 5:08 pmHello Mirillis Team,
so I have been having an issue with Splash Player for quite some time now. The subtitles of some Anime would not be shown properly. To remedy this I made a plugin for your tool whose effect can be seen in the following attachments.
Before:
After:
I would like to make my tool available to other people in binary form, however I understand that Splash Player is 100% the property of Mirillis and hence I would like to ask your permission before I do this to prevent any kind of issue from occurring from me having done this work.
I am attaching this code in case you guys would like to review it.
