Great app but needs tweaking

Please update to display point shapefiles correctly and increase the limit of points allowed per file. Ability to change color of tracking icon would be great too

I use this app daily and love it. It just needs a few tweeks to be perfect👏

Needs improvement

I Love using LizardTech products on my home computer, however this app is so confusing I can't seem to even open any SID files because SID files as you all may know are way over 1GB. I would think about having some sort of way to connect to Dropbox or some other website to have access to rather than taking up space on my iPad. I would also consider adding videos for those newbies like me.

Need to be able to get shape info

Love the app, but need the ability to click on a shape and get a popup with the data about the shape/point (ie, address, desc, street location, etc). Otherwise, great job....can't wait for more updates.
