Feature request: make it possible to add unique constraints from the GUI

Now my only option is to resort to manually writing SQL (and copypaste create table queries for adding unique constraints to existing tables). I would like to be able to do it easier, from the GUI, for both new and existing tables.

I think that pvanek is no longer actively maintaining this version. If you use the Linux version, or can build a Windows version from the sources, raise this issue against rparkins999/sqliteman. I'll take a look at adding unique constraints to table creation when I have time. Adding unique constraints when altering a table is much more difficult, because multiple rows already in the table may have the same value for the key.

@rparkins999 I spent one hour trying to remember why I made this feature request and couldn't. Surely I needed it for some small pet project of mine, but I really can't remember any details. And I surely didn't need it again after that, so feel to assign a very low priority to it if you think it's worth adding.
