Is your feature request related to a problem? Please describe.

The tokenizer is 'dumb' in a sense that it tokenizes any input even if it includes tabs/spaces but later throws validation errors on save.

Describe the solution you like

If the input is trimmed before it is tokenized, user experience will improve because we will no longer have to go back, search for invalid tokens, delete them, and re-add them w/o blank spaces.

Describe alternatives you considered
