Cloning node-red-dashboard elements

While you export-import node-red-dashboard elements to new flow, its automatically merging with original (elements in groups, groups in tabs). Because of same uids, i think.
Here is python script for assign new uids for groups, tabs and rewrite 'group' parameter of ui-elements that you want to import:

import json, random

replace_dict = {}

def generate_uid():
    prefix = random.randint(0, 0xFFFFFFFF)
    postfix = random.randint(0, 0xFFFFFF)
    return '{0:x}.{1:x}'.format(prefix, postfix)

filename_in = "exported.json"
filename_out = "for_import.json"

with open(filename_in, "r") as read_file:
    data = json.load(read_file)
    
for item in data:
    if item['type'].startswith('ui_tab'):
        print(item['id'], item['name'], sep=' : ')
        new_uid = generate_uid()
        replace_dict[ item['id'] ] = new_uid
        item['id'] = new_uid

for item in data:
    if item['type'].startswith('ui_group'):
        print(item['id'], item['name'], item['tab'], sep=' : ')
        new_uid = generate_uid()
        replace_dict[ item['id'] ] = new_uid
        item['tab'] = replace_dict[ item['tab'] ]
        item['id'] = new_uid
        
for item in data:
    if item['type'].startswith('ui_group') or item['type'].startswith('ui_tab'):
        continue
    if item['type'].startswith('ui_'):
        item['group'] = replace_dict[ item['group'] ]

with open(filename_out, "w") as write_file:
    write_file.write(json.dumps(data,ensure_ascii=False))
