While working on this project, there have been few points that we tried to implement or at least we thought it would enrich the tool. One of them is adding an additional feature for the export function such that data file can be saved in a specific directory by browsing the location.
This directory selection option was also lacking when we tried to import file from the local directory. So far we are doing it using manually data list which is certainly not a good practice. Our plan was to use well known Jquery autocomplete property. Working in this area in future would be useful.
We also thought about the alternative of importing a whole XML file. It would have been great to have the opportunity to select only a specific portion of the file selecting target tags, in other words- selecting the subset of XML file based on chosen tags.
