### 5/5 — 引き続きご意見を

*2022-01-06*

以前1行メモについて意見した者です。
採用ありがとうございます！
こういうことは初めてだったので正直おどろきました。本当に重宝しています。
さて、なぜ私がまたレビューをしようと思ったかというと1行メモの改善についてです。
メモをした時に反映させるためには、「完了」のボタンを押さないといけない仕様になっていますが、メモを入力し終わった時に指が下の方にあります。そうすると「完了」のボタンを押すために指をそこそこ高い位置に持ってこなければならなくて、メモを入力しても「完了」のボタンを押すのが煩わしくて結局使わない機能になってしまいました。
私がこの度製作者様にお願いしたいことは、
「「完了」のボタンをキーパッドの近くに配置する」という改善です。お願いします。

**Developer response:** saiですね〜 様
お待たせ致しました。
本日、1行メモの入力フォームを画面下部（キーボードのすぐ上）に表示するように対応を行った、バージョン3.2.0をリリース致しました。
バージョンアップしてお試し頂ければと思います😊

貴重なご意見を頂き、いつもありがとうございます。
これからも改善を行っていきますので、ご利用よろしくお願い致します✨

バージョンアップ、再レビューありがとうございます❗️
確かに、大きいサイズの端末では、画面の上部に表示される入力エリアや完了ボタンをタップするのは面倒ですね。
貴重なご意見を頂き、ありがとうございます。
入力エリアとボタンを画面の下の方に表示するように改善してみます❗️
次回のバージョンアップまでお待ち頂きますようお願い致します🙇‍♂️

saiですね〜 様
お待たせ致しました❗️
本日、名前などのメモように1行のメモを登録できる機能を追加した新バージョンを公開しました。
アプリの設定の「1行メモの表示」より表示設定を「ON」に変更して頂くと、計算結果の上部にメモが登録できるようになります。

デモ動画をFABoLLのTwitterでアップしておりますので、よろしければご覧ください😊

「#CalCal #使い方 #1行メモ」で検索して頂くか、
設定の「Twitter of FABoLL」よりFABoLLのアカウントへ遷移して頂くか、
URL（https://twitter.com/CaMirror/status/1387888748029829120?s=20）を入力して頂ければ、ご確認いただけると思います。

また、ボタンタップ時のアニメーションも改善を行ってみました。
タイムラグが少しでも改善したと感じて頂ければ良いのですが…😓

この度は貴重なご意見を頂き、ありがとうございました。
これからも改善を行っていきますので、ご利用よろしくお願い致します✨

saiですね〜 様
レビューありがとうございます❗️
アニメーション部分を改善する事でタイムラグが改善できるかも知れませんので、タイムラグに関しては、少し調査させて頂きます。

「計算結果の横に名前を入力できるように」と言う事ですが、一時的に付箋を付けるようなイメージでしょうか？

計算結果部分の上部に、計算式のような感じで小さくなりますがテキストを入力出来るように次のバージョンアップで機能追加させて頂きます。

貴重なご意見を頂き、ありがとうございました。
今後ともご利用よろしくお願い致します🙇‍♂️
