Thank you for all the great work you’ve clearly put into your wonderful app. I’d like to suggest adding a feature that allows users to open multiple books, folders, or files at once by selecting all or selecting multiple items. This would save a lot of time, especially when dealing with a large number of files. Thank you for listening to my previous feedback as well—you’ve improved the app so much! 🤎 ### 5/5 — Gets the Job Done *2026-07-28, version 26.5.0* It takes notes easily on the cloud or no. The writing of thie review however is bad. I can ot see what is being written. ### 4/5 — Crashes Automatically *2026-07-24* NW Pro crashes(closes) itself automatically ### 1/5 — Dejo de funcionar *2026-07-14, version 26.5.0* He pagado por esta app, y funcionó bien por unos meses, pero ahora ha dejado de funcionar por completo, he probado de todo y simplemente no ha vuelto a funcionar, entro y se queda congelado, no responde ### 1/5 — From Great App to Complete Garbage *2026-05-27, version 26.4.1* Before, NotesWriter used to be a great app for marking up drawings and adding notes. It was simple, reliable, and actually useful. Now it’s a piece of garbage. The app has become frustrating to use. Really disappointing to see such a good app go downhill like this. ### 4/5 — iPad側の環境？ *2026-05-21* 手書きの精度もよく、日本語も検索できるため、便利に使っております！ アップデート後に使いづらくなった以下の2点を元にもどせませんか？ ・何年か前のバージョンであった、ページ送り用のスクロールバーを復活させてほしい。 ・ファイルアプリからPDFを開いた時、空の新規ウィンドウを作成するようになった。（PDF自体は最初のウィンドウに開かれています。不要なウィンドウだらけになって邪魔） 以下は要望です。 ・表示の「左から右へ」などの設定を固定にしたい。 ### 4/5 — 急に大幅改善 *2026-05-14* 前バージョンのこのアプリはひどいバグがあったりしてお世辞にも有料アプリのクオリティにしては不満が残るものだった しかし今回のアップデートでバグ修正にUIの改善を通してかなり使い勝手の良いアプリになった 今のバージョンなら十分満足できる出来だと思う ### 5/5 — Great for construction *2026-05-11* Big fan! I’ve been using this app for a few years for construction drawings. Making mark-ups, doing as-builts and filling out forms like time cards, hazard assessments and expense reports. There used to be a feature where when you selected something, there was an option to select more items to group them together. I found that tool VERY useful for overlaying things from one print to another, though it didn’t last long. Would it be possible to get it again? A scaling tool would be great, if possible! ### 1/5 — Worst stupid update *2026-05-11* Why r things all changed and messed up and you cant even choose which pen to use when it’s half screened?
