The more we know about your system and use case, the more easily and likely we can help.

Environment info

• OS: Windows 10
• App Version (Lepton v1.10.0):

Description of the problem / feature request / question:

The default format is : [ title ] desc #tag1 #tag2 #tag3

Is there any way to write the tags like '#tag1/subtag2/subtag3#' ?
And then the "TAGS" should be :
layer 1: tag1
layer 2: subtag2
layer 3: subtag3

For example, in this screenshot below:
the layer 1 tag is "linux",
the layer 2 tag is "service",
the layer 3 tag is "squid" and other.

It is like the folder layer.
