I am testing RTM few days now, its simplicity makes it ideal for my use in small business. I dont need anything more complex. I am even willing to pay for this product, but it would not solve the isues it has. Maybe are these just small bugs that could be done, and maybe i am speaking about new product for such use. The SW market lacks such simple management solution for small businesses. I am keen on upgrading to Pro, even paying more, contribute to development and translation (Slovak language). I am sure you can fill the hole of 80% from small businesses which need such solution immediately
The issues i find most critical, when using RTM as management solution.
Case study:
Manager: assigns a job to be done, the date, and leaves comment using notes. Sends this request to an emploee.
Emploee: recieves a job and has unlimited rights. He can change the date set by manager( very bad), he can delete and edit managers notes (bad), he is able to write his own note (good) and able to change it or delete it anytime (+/-)
Manager: Is the only authorised person to change the date, but he cannot do it (bad) he cannot comunicate with the emploee/emploees group through the notes, because he cannot add more notes to the job he created when already sent (very bad)

- the locations cannot be shared across the company, and therefore when manager creates a job assigns the location, emloee does not see the location in his recieved job.

I will love to use such simple solution, it has very good features, but needs a small improvement. You do look like a serious, young and flexible team so i am willing to cooperate.
