I get `Error opening file /<path>/index.html: No such file or directory` <path> is the path to the directory that contains the markdown file I'm trying to load.
If I open the plugin preferences and change the template to "template.html" I get a different error:
```[general] template=/home/ventsyvelev/.config/geany/plugins/markdown/markdown.conf [view] position=0 font_name=Serif code_font_name=Mono font_point_size=12 code_font_point_size=12 bg_color=#ffffff fg_color=#000000```
