Visitor Visa, another application

My partner and I used to live in Spain together and 7 months ago I returned to the UK for work. She is a non EU national with residence in Spain.
She currently has a 6 month visitors visa (we had to apply for this as we had been together less than 12 months, so couldn't apply for a partners visa) which expires this Feb, and has been over to see me a few times during the previous 5 months.

She still wants to visit, as our relationship is going well despite living in different countries and my question is this.............

Will she be okay just to apply for another 6 month visa to continue her visits? She doesn't want/need to relocate and for the next few months we will see on the relationship front as to where we eventually decide to live.

Any thoughts?

Thank you, I did see that but felt it really didnt answer what I was looking at.
Are they happy to issue another 6 month visa just after the previous one expired so she can still come over for a few days now and then? Or would it be better to wait a few months before applying again?

If she can show that she has only visited the UK for brief periods during the 6 months it would be entirely reasonable to make another application as soon as she likes.
Her proof could be, for example her payslips to show that she's still holding down a job in Spain, as well as copy tickets or boarding passes to show the dates of travel.
