Perfekt, hier sind trotzdem Vorschläge

So gut wie alles kann ich damit machen, bis auf .plist Dateien bearbeiten. Ich brauche momentan 3 Apps: Runestones, plist Editor und irgendeinen file viewer, der order öffnen kann, die iOS nicht erlaubt zu öffnen, wie .app. Ich verstehe, dass dritteres nicht wirklich zur App passt, aber .plist als Option wäre super. Das hier soll trotzdem Lob sein, meiner Meinung nach die einzig gute text editor Option im App Store.

Crashes on Apple Vision Pro

As soon as I open it up and start to type anything on my Bluetooth keyboard, the app instantly crashes. I brought this up to the developer on X, but he completely ignored me. I guess he cares more about making other little pet projects than fixing his existing ones.

Lovely

Can finally write down the 1st 10 million digits of Euler’s number and the 1st 10 million digit of pi in the same file easily

Awesome text editor

With direct access to iCloud file system on its free version!

Almost perfect

I really like this coffee editor. There are a couple of limitations, which Textastic has that would be great on this app, such as having tabs to fast switch between files, as well as a better system for syncing with Dropbox or Sync. The fast tab switching makes it really easy to compare versions of code.

Otherwise it is great!
