I'd recommend 4-6 FSs. If you have a quite complex unitframe, I suggest to make sure that FCF frame is on a higher frame level and strata than ur health bar, frames and textures, e.g. unitframe's border and others.
As I said before, there are 2 modes, by default floating is set to standard mode, to switch to fountain mode you need to do this:
If you write anything else than "Fountain", default mode will be used.
ATTENTION! .Offset was renamed to .XOffset
Feedback spawns symmetrically at two points, to manage a distance between two columns you can use .XOffset option:
Number can be either positive or negative, for fountain it better be positive . By default fountain's x-offset is 6 and standard's is 30
NEW! To move feedback's spawn point up or down you can use .YOffset option:
Number can be either positive or negative. By default y-offset is set to 8.
NEW! From now on you can make text float either upwards or downwards, to do so you have to use new .YDirection option:
Should be either 1 or -1, if you choose 1, text'll float upwards, if -1 - downwards. By default direction is set to 1.
You can adjust how long it takes for a text to float and disappear, default value is 1.5sec.
Some of the events can be ignored using .ignore%event% option. By default all the events are displayed.
