Currently when editing metadata manually I have to type every entry manually, even when the entry isn't exactly new in my RomM-instance. This makes editing pretty error-prone and tedious, with the risk of filters not working correctly due to typos.
Describe the solution you'd like
It would be pretty handy to get suggestions when manually editing metadata, based on already used values in your RomM-instance.
For example, in the screenshot you can see tags like 'Nintendo', 'a little bit of...' and 'Puzzle League'. When editing other games I would like those to appear as suggestions when typing the first letters of the entry.
Kinda like;
Companies-field: 'Nint' --> RomM-suggesting 'Nintendo' --> *me pressing the Tab-key on my keyboard to confirm or typing further and RomM hiding the suggestion once the typed text deviated from the suggestion or the user presses the Esc-key on their keyboard. Another option would be like how the 'Game modes'-field is constructed, as long as it's still possible to freely type instead of getting locked down like that field.
Describe alternatives you've considered
The alternative would be to copy-paste entries from e text editor, which would require to open up one and prepare entries in there and constantly copy-paste stuff. It's doable, but gets annoying quickly.
