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.
